Options for protective storage for winter help

I'm on Kerr lake here in Va. and a lot of the Corps and state parks here have farmers near their entrances that have put up 3 sided shed type buildings that they rent out, prices seem to be between 240 and 360 for six months.
Most dont advertise or have business phone listings, you may need to just take a ride past a few.
M'lady said there used to be someone doing that at Glendale, Prince Gallitzin state park, but she hasnt been there in quite a few years.
