Thr Fire/Rescue trucks here in town all have big US Flags flying from the tops of the cab. Gives me a lump in my throat when they scream by.
Many of the dpet.'s in the DFW area do this as well. Lots of the 'burbs the trucks have a staff at the back of the truck with either a 2x3 or even a 3x5 flag flying. Very cool to see.
Speaking of flags, we spent the day at a renaissance fair. Bittygirl got a pink conical "princess" hat. Spiderboy and I got matching wooden swords, and I got a 3x5 Jolly Roger to fly from the pole in the front yard on special occassions.
