I know it's frowned upon for the most part, but quality, upper level mens recreation ball keeps me working every other day.

And I just started working the Pro Am circuit, officiating players like Smooth (Pistons), Demarr Johnson (Nuggets) & college players/grads keeps my game pretty fresh!
I really believe officiating this high caliber of -above the rim- basketball is going to make officiating varsity hs games much more easier. Using the 24 second shot clock, 8 seconds & illegal defense almost feels like working in the league... well we still call travel though
