The problem is that tarps don't last long around here, and a medium

OTOH, what's 1200 sq-ft of space constructed cost....


I have no idea these days, but they probably spent less to build that
building than a 40' * 50' tarp costs now. A 'finished' tarp is a
couple feet smaller than the advertised size so a 30' * 40' would leave
a gap all the way around.

I haven't done any big projects in 25 years. Just repairs & remodels
for myself, at two different locations.
