In my complex, we have a big area dedicated to a Basketball court and some Tennis Courts.
Just so happens that the way it was setup, there's a nice size gap between the Basketball Court and one of the Tennis Courts:
and here's another angle:
I rough measured it out to be about 20'x40'
Wellllll, it's a "dead" spot that nobody's using so I figured what the hell? Let's USE it for some racing action!!!
Last night I got my Xray M18 all set and had a buddy of mine stop by with his 1/18th scale truck (don't recall what it is) and we had a BLAST!!! We even had a little audience for awhile too.
