I'm building a dirt gap jump behind my house. Right now its only about 3 feet high, but I'm not finished yet. I want to make it about 4-5 ft high. I'm not sure how long I want the gap yet. My previous jump only had a 4 ft gap, which is lame, and I could clear the whole dam thing without ever touching the landing jump. When its done, its gonna be SWEET!!! If you guys have any tips, I'm not deaf or blind.
