I think something like this is kind of the idea I would like to go for:

HobbyAus - Indy Radio Control Off Road Circuit - Butterfly Farm, Windsor, NSW, Australia

I am a bit unsure about what to do for a driver's stand right now. I have been looking through ideas such as dirt mounds, trailers, catwalk and mezzanine pieces, overseas shipping/cargo containers. I know mostly they are build out of lumber -- I just hate to go get a building permit and have any chance for my property tax increases (beyond the other increases). Plus the lumber itself is not exactly cheap. I am open for ideas on the driver's stand -- we are talking about 1) good value and 2) don't make my property taxes go up.
