Lost black Ray-Ban sunglasses near the moving truck lot at Altoona-Johnstown Airport.

I lost my black Ray-Ban sunglasses while parked at the moving truck lot near the Altoona-Johnstown airport. They must have slipped off my lap and fallen onto the ground when I got out. I've had these for a couple of years, and they hold a lot of sentimental value for me. If anyone comes across them, I would greatly appreciate it!
