In the past ten days, I've put out multiple sets w/750s using 4 different tried and true lures, from castor-based to curiosity. Beaver swims by all. The other day when I was out in the boat, he actually circled me several times and I started to hear the Jaws theme....
The shoreline is covered with overhanging tree branches and I'm still searching for a slide and/or den opening. Very few chewed sticks, but they see him almost every night or morning.
I'm not sure what to try next and would appreciate any new ideas to outsmart this guy.
