XRAY - Model racing cars

I have been blessed with the free use of about 6 acres of ground AND a bobcat (skid-steer) end loader to build my own private RCtrack.
I placed this thread in this section because this track will be built with my XT8-09 specifically in mind. As well as my 1/10th scale Short Course Trucks. (Still hoping for a SC truck from XRAY )

I would like to hear what you all think is the perfect track. But in specific terms such as length of straghts and height of jumps, and distance between the peaks of the doubles/triples/table-tops etc.
Im goin with ten-foot wide lanes and trying to use dirt burms for lane markers. I do not have the budget for the mile or two of drain tile piping.

Im going this minute to get started. I will attempt to post up pictures of my progress this evening.
