I’m in SW corner of Ohio. Minimal snow...winds can be quite stout around here though. The carports I see seem to last a long time...thinking of a 40’X60’ or a little smaller on a concrete pad.
Part of my motivation is cost savings over a pole barn. The other motivation is we have clay here with a high water table. Concerned about the long term problems with rotten posts of a pole barn. The new Pressure treatment is garbage.
