hey guys, i know its been posted on here a few times about how to rig up a piece of pvc or pipe, to a subsoiler and use it to pull and bury underground wire, but i am still a little confused. when you start the run, do you rig up something to hold the roll of wire, at the beginning of the run, and it unrolls as you drive along, or do you just tie off the end to something at the beginning of the run, and somehow rig up the roll to the back of the tractor, and let it unroll that way. i need to run lights to my horse arena, and am hoping to get by with underground wire, and not have to run it through conduit. i am pretty unmechanically inclined, so any help would be great. thanks guys
