Beach Blanket Babylon: Basketball Motorcycle Diaries Edition.
Just a couple of Care Free Chicks giving a whole new meaning to "Drop-Top B-Ball Bobber"... Light-up, Hang Out, Be Cool.
That bike has probably been melted down to make hinges and bolts, and those babes aged gracefully and died. The ocean is still there and has actually risen a few inches.
Upon closer examination of the photo, I see there is no evidence of trappings from a future time...like cell phones, or filtered cigarettes...so we can safely assume these are not 'time-travellers' and that is real boobie flesh and not silicone...
