Why not for summer? My friend has a drop-in entirely made from pallets and planks that we just gathered together, it's about 5ft 5in tall I'd say and it works great for winter. We were going to put turf onto the down ramp part of it and then we'd have a summer set-up, would this work?
I wanted to use pallets for my drop in since I have a hill in my backyard, but I couldn't find any so I just laid plywood down and screwed the pieces together. Threw some turf and construction fencing on it and its good to seshh
