Ok so I used to ride BMX like 12 years ago, got out of it and just did the life thing, now I am have started riding XC but have also found a real interest in Dirt Jumping. I live in Houston TX and there are no trails worth **** here and I would love to build a nice spot. I have been reading like crazy on every piece of web info I find (here, Pinkbike, IMBA, dirt-jumping, etc.) and am getting a basic idea and view of differnt jumps and the basics but I had those as a kid. So what I am looking for is info on making trail lines flow, designs of things like rollers, doubles, tripples, their spacing, height, lip design. Any info is greatly appreciated. I have a spot to build on (20 acres) just looking for all the info I can get. Thanks guys.
