Oooh - I'd get one!
I agree with Carole & Softhug static cling for inside the rear window or a magnet (not huge) with the logo would be great!
Anky's idea for a card would be good too - I was at the post office last week & this woman had a newfie crammed into the backseat of an Escort - I would've put a BPO card (carefully) on her windshield! Maybe we could come up with a cute phrase..."you've been spotten by a BPO"...or something?
I'm on medical leave from work - I could brainstorm some stuff if help is needed! (I'm seriously bored & need some mental stimulation!
)
What'd ya think?
