My track idea...

[cowfish_29]

For the last few months, i have been thinking. Ive always wanted an off-road style track to run my subaru impreza wrx on, but i always ruled that out because Bit char-g cars are strictly clean and sterile cars.
So, i think i figured it out.
-I will use a 4' by 8' piece of plywood for the base.
-I will mark off the track outline with cardboard strips
-Then, i will use water putty (plaster-like stuff.. sandable) and roughly but somewhat flat-like, spread it on.
-I will let it dry and sand it down smooth, and with the aid of a broken bit char-g car, i will check clearance on all of the bumps to make sure the cars can get over them.
-I will paint the track a dirt brown base color, highlight it with grass type colors, ect ect.
-I will get balsa wood and replace the cardboard borders to the track, glue them in, add racing sponsor decals, ect ect.
-I will get scale sized trees, shrubs, rocks and other stuff for the outside of the track.
-I will use the idea that TheFanMan and I have thought of... making a lighting system out of a series of LEDs and making stadium-type lights.

TheFanMan is also probably going to help on this, he's got lots of good ideas and is a great artist for this kind of thing.

So, everyone, tell me what you think, and if you see anything that will go wrong with this idea as of now... thanks!
