I have a restaurant with an outdoor patio that is 40' long but is 15' on one side and about 20' on the other end. Its seats about 50 people and we are looking to cover 80 to 100% of it. We don't mind maybe not covering a few tables on one side of the triangle type area. It's a summer place so we want it to cool down our patrons and protecting them from rain is secondary but important.
