Anyone wanting to go to DC for the rally hold a Ron Paul sign on the side of the highway with your thumb out. I'll pick you up if i see you, as I'm sure many will.
I also suggest that when we pick this date we find people who have room in their cars. Then find out who they can pick up and take along with them and drop them back off. I've done this for other events like big concerts. Effective, fun, and you get to talk to each other and meet other Ron Paul supporters on the way. How fun!
Could actually save money by chipping in together to rent buses at these gas prices. Not big, proper buses as you can only get them with drivers, but the biggest we can get (probably long vans). Might discuss it with your meetup.
