for next yr im thinkin about building a light short rail(8ft long) but really tall ( about 8 - 10 ft high) and it needs the height to be adjustible and it needs to be moved pretty easily cus we hafta take it like a mile through a trail all up hill so i was wonderin what material i should use for the rail thats durable that i can leave out all winter and how can i make the height adjustable
