yea you definitely need to specify where you are.
i have two 8-foot long boxes, one that hasn't left my garage since i built it. i built them both over the summer, then we never even got enough snow to sesh them. the plastic alone cost 150 bucks for them though. i'd def sell one, i just realized that i'm moving 3000 miles away and have no need for a box.
the boxes are in New York, btw.
