Does anyone know of any information on making a RC track, something that explains everything from beginning to end?

For example, I heard of someone using a roller to pack the dirt after its been laid, is that the best tool, is there something better? How or or what is the best way to plan for jumps in a track, as far as ramp placement?

I've seen RC Car actions website, describing a few things, (http://www.rccaraction.com/rc/articles/howto_track.asp), maybe one or two others, but is there anything else out there with a little more information that is listed there?
