Can anybody suggset a good track builder program, possibly a free one?
I have seen some links here and there in other threads, to some programs, but none of them ever work.

How much of an area are you trying lay out?

My buddy and I have a lot of space to build a track this summer, and since I have never built one before, I want to make sure I get it right.
I think we have about a 100'X100' area, made up of very fine dirt that has a sandy consistancy when wet, but dries rock hard.
I was hoping to find some sort of track building program to design a few tracks on.

There is a thread here with alot of photos of diffrent tracks, study some of those then just draw out your ideas

I was going to say that also. Make your lanes atleast 10' wide, and set up your jumps first. You run the track for a couple of hours with just take off ramps. As you are jumping keep marking your landings. You wan't to put your landing ramps in the areas your landing. Remember to start the top of your landing behind the marked landings. This way you are landing on the downslope of your landing ramps. What type of vehicles are you going to be running? If you give me your exact dimensions I would be glad to help with layout, if your intrested.
