Gordon, you're KILLIN' ME!
The MBBA . . . Massachusetts Beach Buggy Association, right? Back when a "Beach Buggy" was anything with fat funny tires and a fishing pole strapped to the side with pipe hangers.
WOW, I remember driving in the back of my parents Chevy beach wagon and seeing a similar (I thought so, anyway) wagon with what looked to me like cartoon tires on it . I nearly climbing out of the window to get closer to it. After that, every time we went out for a drive and got farther South than Weymouth (MA) I would start looking for those MBBA stickers on the backs of cars/trucks . . .
Cut it out, man! You're just killing me with all these long forgotten memories . . . The MBBA! I was sure that the brain cell containing THAT memory had died LONG ago!
