Set out a beaver/otter line last weekend with my partner. He checked them and pulled nine beaver on the first run. However, at two of the ponds someone came in and put sets less than fifty feet from ours. I for one never set on a pond that someone else is trapping. We did find one pond, several miles from the ponds we already set, where someone had set. We moved on leaving it to that individual. Whoever set up on the ponds we already set, had to walk by our sets to get to where they put theirs. Frustrating.
