Woah... Ted... nice track. Did you build it yourself, or buy & rehab an old commercial layout?
I would probably be showing slot racing as a hobby if my buddy's 50 foot 3-lane routed track wasn't almost an hour away. Several guys show up every Thursday night to race on it and he's got computer lap timing/counting, but I haven't joined in yet.
The only thing that qualifies as a hobby for me at this point is my collection of diecast cars. It's fairly substantial, but I'm so non-serious about it, it barely qualifies. I basically only buy what I like, when I can find it relatively cheap, and with no regard to value. Mostly race cars, mostly 1/43rd and 1/18th, and I don't save the boxes and mounting bases. I never have it all displayed... no room. Usually just have 10-20 out on top of a chest.
Don't have any photos... found this pic on ebay... it's one I have... 1/18th scale.
I used to race 12th scale radio control cars.
