I don't know how old you are, but these people are NOT funny.
There is currently at Blockbuster a video, The Weather Underground. I recommend it for reasons quite different from those of its producers.
No they aren't. It's really too bad the Convention is in New York City where the peaceable law abiding folks are disarmed.

And for these folks hemp is the only way to go.
