I think they used a tractor. Sunday afternoon they had the truck hooked up to something big (that I didn't pay close attention to at the time) and had pulled it around the front of the building (it had been on the stove when we drove by in the morning.) Then they put it back on the stove!
ETA I asked the Husband and he confirmed they had a tractor out there, with a forklift attachment thingie on it. Creative ;)
