Very cool...
We had a slot car emporium a couple blocks from my house with full size tracks for 1/24 and 1/32 cars. Track rental time was reasonable. (50cents/hr, if I remember right).
And I had an HO track the width of the back wall of my parents two car garage. 20 ft straightaway, and a winding road to get back.
We had Busy Bees in Concord Ca. had huge tracks,
1 real big one, right in the center of the store
like 15 turns, rises & drop offs, hairpins, loops, 1 really long straightaway,
after banked corners after the bigger straights
(lots of wrecks at the end of it) like 8+ (?) lanes wide IIRC
had several different scales too 1:18 (1:16) & 1:24 (or 1:25) cars
even a scale dragstrip,
I had a 1/4" plywood/garage box, burned with a torch/sanded & stained
it was like 18"wide x24" tall x12" deep
big open full front door, like a ramp, it had drawers for storage/parts
my stepdad Bob made for me, I was decked out & ready to party/race
it has spots for & carried like 4-5 cars
& all the spares...
I had chassis he soldered up out of welding/brass rod,
trick rewound motors & brushes
really thin/paper tin, light weight bodies
(my favorite was a 33-34 Ford or 40-41 Willys gasser & a 65-66 GT40 road car)
we'd/I'd try custom paint them, even a parachute
that got destroyed easily, when they fly off/crashed
They sold stuff too, cars, parts, wheels, tires, controllers, motors, axles
even custom tracks or track pieces for sale, & consignments etc.
the 1:32, 1:43, HO's & the smaller scale cars, all came a lot later...
It had to be like 1966-71-ish when I was doing it...
It became IIRC 'Service Center'
well known Aftermarket Performance Parts, when it was bought out...
