plain rebar with a washer on top 12 inch on fox coon stake pumping coydogs cross stake with 2 rebar. Howler got a good idea but the ground freezes here. some people use a triangle of steel about 4 inch with a notch for driving the angle your trap chain gets attach to the middle and another chain gets attach to the corner when driven and you pull on it trys to come up flat the other chain is on the corner and is for pulling it out when you move. a small car jack with a notch for the chain link is good for pulling in frozen ground

you can use your pepper spray my 12 gauge with 3 inch slugs works fine
