Currently i am and my friends have all re painted our garage floors, and are current using garden hose to outline a track. it is easy to manipulate and change and large enough to keep the car in the lane. and as far as tracks we just rescale race tracks from around the world primarily f1 tracks. and i guess size wise they are about 400-600sq ft 20'x20' and my next door neighbors is 20'x30 sq ft. i will be posting pics...but we are so proud of ourselves that we will be holding LIVE RACES we are just tuning our cars and getting them ready so to speak but we have already broadcast a few to test. we have rounded up about 6 webcams and cameras we can use so far.
