Would there be any interest in doing this type of trip?
I was working with a couple local geocachers to setup an event up there in late August. I think we may trash the geocaching event idea, but still do the trip.
For those from Ontario (and or interested), I have a ton of info on the Northern Ontario Geocachers forum (thread here). The last post by me is most relivent as the landscape has changed a lot since my first trip up there.
