Q: What do you do when you've got your granddaughter's birthday present all wrapped, packed, and addressed, ready-to-mail but not stamped? Take it to the Post Office of course. But it's Friday night and the Post Office doesn't open until Monday morning, after you get to the airport to return your Budget rental car?
A: Forget the package on the back seat of the car, call and give the nice Budget Lost and Found lady (who is also the nice Avis Lost and Found lady) your credit card number so she can send it directly, by UPS.
I'll let you know when/whether it arrives.
P.S. I'm home...yay!
