Sorry I didn't get to make it out to this, but after being at the shop from 6:30 Thursday morning until 10:30 Friday night I really didn't feel like replacing my water pump to come out.
A note for next year though - I would have been pretty upset when I showed up with all of my pulling and racing gear and found out I had to choose between one and the other because both were going on at once. There are more than work/stock trucks that like to do both - I know last year Brian J, Ed, and myself all had fun competing in both events.
I plan to support the event again next year, and hopefully actually make it out.
