Mike,
I’m still keeping my eyes peeled for new Boulder bumper stickers, and when I see one, I note it down on the b.s. notepad I keep in my car. I see many of the old ones already listed, but new ones keep on appearing. Maybe I’ve seen about half of all that are out there. Some are funny enough that I forget where I’m driving, like “I study ferns, and I vote!”
