I am hoping to try my hand on a few beaver later this year. Looks like a boat load of fun. I try to stay away from using coyote urine due to the fact that I dont know what coyote it came from. If it happened to be a dominate male it could detour smaller yotes from working the set. I had an old timer tell me to always down size one not matter what I am after. If I am after yotes I use fox urine. Fox I will use coon urine. I due use some long distance lures when it gets colder. I like Ohio Valley Long Distance Call by Matt Jones out of KY. Another I like is Caven's Yodel Dog Lure.
