Ron Paul's Campaign for Liberty is involved with this, along with a host of legitimate pro-freedom, small government, sound money groups.  Looks like no phonies to be found.

Then again, watch out for weird guys trying to incite people to do weird and bad things.

Other than that, cheers to you! 

The short time that I spent in that city made me realize that I don't think I could stay there very long, once the novelty of the monuments and museums wears off there is nothing special there, its just as trashy as every other city and worse than many... seems to make sense the seat of our gov't is there.

 Be careful while you're there.
