How long and wide are the tracks? I have the chance to make one myself close to where i live but im not shure how long to make the straight. I dont want to make the track to big or to small. Ive got it marked out at 125 by 76 ft with the laines 8 foot wide. I can go 60 ft longer if i need to but i do have 2 poles in the way. But of what ive seen most tracks seem to be lots bigger and have way to many turns in them.
