so im going to build a summer setup this summer at my house and im starting from scratch so i dont know where to start. i want a ramp with a platform on top with turf on it. down below theres going to be a lip and rails etc... in the winter my yard is slanted enough that i could make a rail garden so i want the ramp a kind of shallow so i can put snow on it or so it collects by itself. so does anybody have angle ideas or design ideas? p.s. this is gotta be snowboard accessible as well with ski.
