The last time I broke some bones was on a motorcycle... I wrecked pretty good & was out of work for 4 months!
In that time, I got into R/C car racing... TONS OF FUN!!!
I went through every kind of car there is; 10th scale on-road, buggies, monster trucks, but what I really fell in love with was 1/8 scale nitro on-road racing!!! (75+ MPH)
There are a few tracks here in LA, the one I used to hang out at 'Crystal Park Raceway'
is where a lot of factory sponsored racers hang out & practice.
If anyone here knows about 1/8 scales, I raced Swiss made SMP Slide's. They're all aluminum (not plastic)
