No, they don't. Once a guy followed me into a car wash to find out what it was - and he was in a convertible with the top down! We drove the UPS and FedEx drivers nuts when we first got them.
But there must be others from out east living here. I originally tried to get just QUAHOG, but it was taken. Then she tried QUAH0G - with a zero instead of the O. That was also gone. so it came down to 1QUAHOG - and Douglas has 2QUAHOG.
Once, when we were in Rhode Island, some lady commented that she didn't know there were quahogs in Michigan :)
