Bill, I'll be the first to point-out that you're not prone to exaggeration but you have to admit, that story sounds a bit urban myth-ish. Pulling into a Walmart fully-suited? Sure..... Not taking off the lid and doing your shopping with the visor down, even through checkout?
I'd be blinded by fog before I made it in the front door lol. If the cops did arrive and investigate, leading to a 17 hr detention, then something else had to be up.
EDIT: post a link! That sounds like a funny enough story to read.
