John,
I may have lost all opportunity to opine on the logo when I failed to "get 'er done" last year, but . . .
What do you think about putting "Chevy" under the STOVEBOLT part on the first version, and "GMC" just above the VOLUNTEERS part?
I think they're both very cool. I like the first one best, along with your personalization idea. Sign me up for 10 at least!
