Well, i myself am getting ready to make my own track as well, what dude suggested, about making a flat track first, i think is a very good idea, and make jumps later, you would have a better time figuring out where you want the jumps, more advise, i read a persons tip to someone who had the same question as you, it was put, as a suggestion, to draw it on paper first, then go out to map it out, you could easily start just by mulching the ground, and then packing it down, different ways to make the linings, spray paint if you just need to see, or wood, or dirt mounds what not, then on to the jumps, dirt dirt and more dirt, fun fun, alot of shoveling, can be a lot of work i think, I'm getting ready myself, and i am using the tip when i start that i just read, about a flat track, a very good idea!
