I'm moving soon into a house. I've always lived in apartments or in houses in the city with 10' by 10' cement lots for backyards. So I finally have a backyard and a super long driveway in which to build a quarter pipe and what ever other ramps I can afford. There is also a brick wall at the very back of the yard that will be becoming a sub box when I build up the dirt below. I'm excited. Anyone ever built a quarter pipe? I want to build a decent one that will last me. If you did how much did you spend on it? was it difficult to build? Thanks for your input.
