Kristen, if I could make it up from San Antonio for lunch, I'd be there. I think I'm the designated babysitter that day, and for some reason my wife frowns upon my stuffing two car seats in the passenger side of either the Cobra or the GT40 (picky, picky).
It's funny to read about your husband forgetting to close the garage door...but at the risk of starting a "gender thing," I'll say no more.
You might consider buying a California Car Duster from Pep Boys. I used to towel my cars off periodically when they were simply dusty from sitting around, but a CCD will do the same thing and seems to be less likely to scratch the paint. The ideal way to remove the dust is a quick blast to 140 mph, of course, but that's not always adviseable (especially in residential areas
)...
