Awhile back, we had a saltwater get together on one of the clinker islands.
A couple guys brought them unfoldable tent/shade canopies (like we had at Cresent), and we had several coolers, and
some brought chairs. We also brought tables and a couple of gas grills.
It turned out pretty well, not as many folks as in a slabfest but probably 15 folks.
So, is certainly achievable for a slabfest at a none unilities place if we plan correctly .........
