There are others but I don't have time to look them up just now.
Gee I wish I didn't have problems with location.
I wouldn't worry about deer or bears just now.
Neither are a particular problem with small foothold traps .
Use as much wire or chain (not rope)as needed for your particular trap location.
I don't use much wire because I don't want the critter to get a running start when its trying to pull out of trap.
I use 18" rebar stakes and only need 1 to hold any critter I trap.It depends on the terrain. Might need 2 stakes in sand.
Good luck
