Bridge Over Troubled Water

What's up with those bumper stickers that say "have a Cape Cod Day"?
What does that mean?
Can they be more specific?
This week it could mean sitting in bumper-to-bumper traffic on Palmer Avenue, paying $20 for beach parking at Old Silver, and have to boil your foul-smelling water.
The bumper stick on my car is a nice direct admonishment. It says "Buy Cape Cod Grown."
I see that some large, timely, June bugs have gotten into the house.
Hope they don't try and drink the water.
