Ah - we have a rogaine on in SA that weekend anyway.
Well I've just realised it clashes with State League too, but I was quite willing to sacrifice that until I remembered that the closing date for the school reunion is 2 days before and I will be in full flight seating and catering arrangements mode. Had it been the week later I would have happily missed the actual school reunion (after taking all the bookings and hearing all the excuses possible) but I can't leave then for what I suspect would have been 5 days. Feeling really deflated now.
Maybe, for a rogaine fix, you could hitch a ride with someone who's coming to the Deceptive Lands in May...did you ever orienteer on the Burra maps?
Interesting. There's a big range there but also a lot of very flat country, which won't be easy to locate controls in.
