Denver Airport Car Rental

May be I am just from California, but it was a bit strange for me to see all these trucks just waiting to be rented. We wanted something with a trunk to hide our luggage since we were going directly to the tradeshow, and we had reserved a full size car because we had four people. We get there and most of the vehicles are trucks. We finally end up with a PT Cruiser that is somehow considered a full size car.
