A few bear encounters in the BWCA here as well,always camped on islands,smaller the better,still the rascals would get a whiff of dinner,usually a fish fry if they were down wind in the area and swim out to visit,had one lay a scent trail from the parked canoe up to the tent,we could hear him pissing close bye marking the area,only a canoe paddle for defense,another pulled our food pack outof a tree,"some beech" sure liked our raman soup packets.
Always had whistling bottle rockets in my pack,came in handy a few times.
