Before scanners and the internet, I hit a .501, and a .499, but never a perfect tree. On a pro tree I hit a .47 something, but the guy next to me red lighted and I left on his move (street race instinct ) so I don't know if I'd count that. My R/T's in the Buick suck, I guess it takes a while to get all that weight moving, maybe I should start leaving on the first bulb
