How about a "We built these roads!" protest. To counter the repub theme.

[Waltons_Mtn]

Everyone put a sign that says "We built these roads!" into their car window and protest on the public streets of Tampa. If we could clog up the streets with traffic and not let them get from the airport to the convention it would be great. Occupy the Highway! Just my stupid idea.

1. The things THEY say in Tampa will provide lots of new entertainment

Even Akin's magic vaginas will be buried by a whole host of new insanity next week.

and I heard it might rain...

2. It's not a stupid idea at all.

Don't ever call your own ideas stupid -- that's like stomping on
a little plant, just when it's trying to make a flower. Each of us
is a fountain of ideas. Some are silly and some are wild
and some are nonsense and some are brilliant.

I don't mean to lecture.
This is a lovely little book about ideas:

3. Paste a similar sign on the very facility where the RNC is to be held.

It was revealed that it, too, was built with a sizeable government contribution.

4. NOT a stupid idea at all!

I think it's a great idea!

5. Give them a reminder by

using the ARRA signs as a template!
