My son and I were having lunch at the Stanford Golf Course restaurant some years ago. It has an open ceiling with nice open trusses. SPLAT! A mouse fell off the truss and landed on the floor right next to us, knocked out cold.
Another time, my buddy and I were exploring the rock shoreline of the island next to ours when we came across a small boa constrictor. Buddy tried to pick it up and he got bit....he thought he was going to die.
He's the only person I know to have ever been bitten by a wild boa.....LOL!
