The gate.
Our campground has a security gate out front to prevent unregistered vehicles from entering.
One lovely day, three ladies were riding their bikes around the grounds. They came around the back route to the front of the park, and wanted to continue their journey by going past the gate.
They were riding single file, and the first two girls went around the gate, like you would expect any normal person on a bicycle to do.
The third girl, however, did not alter course, and rode straight ahead.
Straight ahead, and right into the gate.
Her body colliding with the gate caused its arm to snap, leaving our gate with half an arm, and its other half dangling downwards.
Normally, you would expect the rider to stop, hop off the bike and check the damage. This girl just kept riding, seemingly unfazed.
