Made it out to the track tonight.  Track was really green and dirty and slick.  Had a lot of fun and a couple of really wild spin outs smoking the right rear tire.  Made a few adjustments and really picked up speed taking a second off my lap time and getting just about to where we were running last season on a green race track.

The last run out, my dad and I switched karts, similar setups in them, but they handle a bit different, he was slower driving my kart, I was faster than he was in his kart.
