Who else USED TO wrench outside?

Oh yeah. Had a locust tree with a huge limb 10 feet off the ground. Used a chain fall to pull motors. Had a bob cat front loader and dug a trench the length of my 67 camaro and just wide enough for the tires to not drop in. lined it with burlap sacks with a bit of local hay inside. Drove the car over the trench and proceeded to work on the trans, shift linkage and rear end. Didn't know any better...worked with what I had.
