Bulletin #6

Redid the start lists, inserting a few people and making some other adjustments. Check your time, you may have moved by a minute or two (though I don't think in general that anybody got moved much earlier).

Trail-O will follow the Classic, and will be done in waves of five minutes each (limited time allowed on the viewing platform), with up to ten people in each wave. There will be a signup sheet for the waves at the event site.

Party will be... somewhere nearby, arrangements will be finalized shortly.

Night-O will use a quasi-mass-start format at around 20:30.

Bulletin #4

Surprise! Registration is now closed, those on the entry page made it in. If you think you entered but don't see your name there, or if you were snoozing and missed the unannounced entry deadline but think you have a plausible reason why you should still be able to enter, send you sob story to, and the corn wizard tribunal will consider your plight.

Start times will be announced tonight (Aug 30). Probably.

Bulletin #3

Mapper Notes

The competition area lies near the Connecticut river. Typical of such anastomotic water courses, the terrain sits on a fluvial terrace of an alluvial plain.

The soil in this riparian zone is a rich crevasse splay, historically praised for supporting healthy stands of Nicotiana tabacum. However the vegetation encroaching the terrain now is a rather invasive form of Zea mays. Entering these areas is forbidden, and has been mapped in olive green.

Given the championship level of the event, brand new super high resolution LIDAR scans were taken. In keeping with the recent trend of smaller and smaller contour levels, the contour interval was set to not 5m, not 2.5m but a world beating 1m. Moreover, every half contour form line visible in the LIDAR data was also kept. So competitors can expect accurate contour detail to better than 0.5 meters.

In fairness to all competitors, the most recent official map of the terrain, 100% fully field checked as of July 5th, 2017 is available at the following link. (Just the left part, ignore the section on the right.) As usual, this map is perfect.

However, due to the excellent local growing conditions in the last few weeks, some minor vegetation changes should be expected.

Course Setter Notes

All courses, regardless of category, will fully utilize all areas of the mapped terrain. Nevertheless, competitors can be assured that the climb for all courses has been kept well below the CMOUSA limits.

To help the inexperienced, most course legs have been designed to provide at least one route with handrails. However expert orienteers should be able to find corridors that will reward a more aggressive approach. Very fast running speeds are expected. Be wary of parallel features. Controls on identical features, close together, may be encountered, probably deliberately.

Since the areas of zea mays are forbidden, there is no need for leg covering. For the night-O, a watch is recommended, and also some mechanism for portable lumens.

As in all international events, use of an internet capable device with a screen during a race is not
permitted. Carrying is fine, just no peeking. Calling 911 is cause for immediate disqualification.

For the trail -O, mechanical aids are not disallowed. Drone use is permitted. However, lack of flying skill will likely earn derision from the crowd and possible loss of the craft depending on where it “lands”.

Sense of humor highly recommended.

And number one rule, above all else, respect the maze.

Bulletin #2

If you'd like to register but don't have an Attackpoint account, or if you don't want to post your particulars on my log, send an email with that information to instead.

Bulletin #1

Due to the retirement of erstwhile organizer PG (necessitated by crippling time constraints of bicycle touring and birdwatching), the event this year will have courses set by Steve Richardson, with organizational assistance provided by J-J Cote.

Some details are still in the planning stage, but:
- We'll most likely have two individual races in the afternoon, a Trail-O, some sort of dinner/party nearby, and a handicapped night race.
- First start will probably be about 3:30 PM.
- There may be some changes to the Trail-O to bring it more in line with international non-corn Trail-O standards.
- The map will, as always, be perfect.
- Entry fee for all events (not counting dinner) is expected to remain at $20.

Embargo: anyone planning to compete in the event is expected to stay out of the designated embargo areas, effective immediately, until the start of the event. In addition, drone flying anywhere in the area depicted is prohibited prior to the event.

Entries: As per usual practice, there will be a field limit of 50 or so competitors. Pre-registration is now open, by posting here.
