Clewiston Walmart Supercenter

Free parking, overnight parking just do not overstay. Busy road. 

Stayed two nights, no problems. 
During day stayed across the street near Wendy's so I wasn't camping in Walmart's parking lot. Came over to Walmart as it was getting dark. 
Multiple places to eat in area including Beef O Brady's

Spent the night in a truck camper had no problems. Late in early out. Dollar Tree, liquor store across the street

Well, poor old Clewiston is like an orphaned child that nobody wants. Walmart & adjoining Tractor Supply are about the only signs of civilization in this old agricultural town. Noisy, gray & dreary, but no one bothers you.
