getcha 4 5ft tall cattle/utility pannels, around 10 6.5ft t-posts and build you a circle trap. it hold a heck of a lot more than 1 hog at a time. if u want mobile traps. i took 3 goat pannels, 2 20ft sticks of 1" angle and built a 4x4x8 trap and welded 5/8" round stock for an axle and got some solid hand cart wheels and it made it very mobile and you can take the wheels off when u get in place.
Very good advice, just build a door and the rest can be temporary.
