Step 1: The Spot.
first, you need to find a spot suitable for your pole jam. you need to find a corner in dirt or grass with concrete around it. make sure that nobody minds you digging at the spot.
Step 2: Start Digging.
sorry i dont have a picture for this step. you want to dig in the corner so that you have a space underneath the concrete to put the pole in. you also should dig out a spot to put the rock in for support.
Step 3: Finishing Up.
put the pole in the spot underneath the concrete and wedge it on top of the opposite side of the corner. put the rock in for support, and fill it with either dirt for a temporary pole jam, or fill it with concrete for a permanent one.
now go shred!
