I’m not fully sure the circumstances this sign is elucidating, but I can tell you I won’t be riding my bike here, that’s for sure.

@superbetsy Crossing tracks improperly may lead to involuntary Superman. Be warned.

But for reals that’s a GREAT sign.

@wklj @superbetsy Not all heroes wear scrapes
@Simplicator @superbetsy not kidding: “Superman” and “Yard Sale” are common lingo for cycling crashes. The latter being such a tumble everything flies out of your pockets. It’s all over the grass like a yard sale :)
