They are awesome traps! I love em! Except I got my thumb in one a little bit the other day and that wasn't fun.. It's fun to watch them go off. Lol I haven't read anything that says you have to use offset jaws in Wyoming. The regs have a snare specification but nothing for foot holds. I've just been told the offset is the best way to go. I've pretty much self taught myself to trap. Lol
