Brick, your post reminded me of a friend of mine from childhood who we called "Rock" -- as in "Rock Head."
Great guy, and one of the coolest cats I ever knew. That goes back a lot of years, and I haven't seen Rock in a long time. We're all in our 50s now, but the last time I was back in that area, everybody was calling him by his real name: Darrold.
Anyway, welcome to the forums!
