Here's an opener I erected behind the ice cream stand i work at during the summer. People around the Outer Banks LOVE to ride around on rental bikes to get around. EVERYONE has a beach cruiser down here, but hardly anyone wears a helmet while riding, probably because its not cool, or they're bonkheads anyway xD.
QUICK! There's a hottie on her bike with her friends visiting from big ol' New York! Give her some southern hospitality!
"Hey, where's your helmet, girlie!?"
She started laughing so much that she stumbled in a patch of sand and totally proved my point valid! xD
What are you waiting for? Prop her up and say, "Hi! I'm James! I should get you a helmet, bonkhead!"
