We checked the locations of the paddle-in CPs by having the volunteers send us a text from their Delorme trackers. They were all in the right place according to the map. However, as you well know, it is always possible that a 25-year-old map might misrepresent the shape of a body of water, especially in an area where Bob The Beaver is known to live.
P.S. Your sense for how to deal with roads on old topo maps shows the value of your years of experience. That caused a lot of difficulties for teams.
roads change or get improperly plotted, even swamps and ponds can change over time (especially the appearance at night). Lakes and bigger creeks tend to stay the same over short (50 year) periods of time :-)
Bearings and 'permanent' handrails are the way to go in the dark in Ontario if you're playing it safe IMHO
Totally agree. My night route choices tend to be boring and safe, and my antennae are up when I'm on trails or logging roads - especially after missing CP1 at a certain RTN designed by a guy from Midhurst.
I have a feeling the shoreline was poorly mapped to start with near CP5. There seemed to be a small bay south of CP5 that wasn't as obvious on the map- the campsite was on a bit more of a point than it appears. Several teams looked for it too far South at night, but it was the only campsite there, and the contors above led into it properly.
Funny how you somehow always manage to end up with beer during the race. Your super=power, perhaps? Please use it wisely: with great power, yadda-yadda-yadda
