Likely NOT locals, All roads around here were actually dry (50deg out) except this 1/8mi. stretch of county road that is shaded all winter. They were lucky they wern't Haulin A$$ coming down the hill to this spot.
I don't envy that situation. I've laid down a few dirtbikes on ice while trying to push it in terms of early season riding in the "spring" and that sucked, never mind a big cruiser motorcycle! No thanks.
