I used to watch it with my dad when I was younger, but I don't really follow it these days. We have a local dirt track down the road that brings in racers from all over the region. I haven't been there since I was a kid though. We also have a local University that has an International Auto show every year and I used to love walking through the vendor area and getting all the stickers, pencils, pens, and other junk they gave away for free.
Hobbies and interests come and go I guess, this one stuck with me from a young are though.
