I've just had two caches in northwestern Ontario published, but they're not in Manitoba and won't show up on most searches even though Winnipeg is the closest major centre...
The caches are about a 20-30 minute drive past Kenora, and requre a 2-3 hour (each way) canoe trip to reach. Little Scovil is about a 2 hour (total) side trip from the route to Troubled Bridge. You could probably do them in a day trip, but it would be a long day. It makes a nice overnight trip, though.
Enjoy.
grnbrg. PS: No, I don't expect many visits to these two.
