You said Springfield. Since you claim to have been all over the world, I assumed (in error) that you meant Springfield, Illinois, not Springfield, Va. I'm not a mind reader. Having traveled the Beltway and 95 numerous times, I'm familiar with HOV-3 lanes, not your slang term of Commuter Pickup Operation. Try speaking English. As far as pounding sand...buddy, I'd rather pound salt. I'll leave the sand to you.
Go ahead, it's your butt ~ Springfield VA is the answer.
