While Matt and I were at Leisure today (conducting a trade) we were checking out the slot cars and I promised to post this link:
http://www.hoslotcarracing.com/

By far, one of the most informative sites for slot cars. Anybody else into this hobby? Lots of fun, not a lot of space. I made the "tuckaway 25 track" for my basement. Works great. Fast and fun 4 lane racing.
