I went to the car wash last week.  Before washing, I pitched:

• 4 fast food cups
• 1 empty pop bottle
• lunch wrappers for two sandwiches
• random receipts & wrappers from the car's trash bag

Hmmmm.... maybe I eat too often in the car?  Or, maybe I just need to learn to THROW AWAY the trash the next time I get out of the car?
