It’s amazing how much trust we have in Plexiglas. I thought about this as I stood on top of a single piece of Plexiglas more than 1,300 feet in the air, looking down at skyscrapers below.This weekend me and the guys went to the Final Four NCAA basketball championships in Indianapolis. It’s become a bit of a tradition since one of my friends has won the lottery two years in a row, allowing him to buy four tickets to the NCAA finals even before we know who will be there.
