I've set a 10CP 3km Holiday Practice Course at the Cherry Hill Nature Preserve in Superior Twp, MI. It's at Cherry Hill Rd, 1.75 miles West of Prospect Rd. Park on the north side of the road in the pull offs, start/finish at the boulder just past the trailhead info kiosk. Difficulty is orange/green/red. Pink streamers, which are numbered. All are set at chest or head level to avoid deer thinking they are treats! Very dry and runnable, except where I buried a few! Game trails are your friend :)
Email me miclimber @ yahoo dot com and I'll send you the map.
I have created a livelox.com
event as well to compare against others. Search Cherry Hill
I plan to leave up until Xmas.
