I thoroughly enjoy reading about, and discussing Austrian Economics and Liberty. Love the Walter Block, Henry Hazlitt and Peter Schiff.
Here is a great outlet for studying such things: www.mises.org
Make sure to help support them by buying books (even though they supply many books for free!)! I would be more than happy to trade books on similiar matters with anyone in my area,(mainly Western Loudoun). I believe the more knowledge one has of Liberty, the better one can explain and debate it with others, so I find myself studying more than partaking in activism.
Although I'm not a big fan "beating the pavement" or door-to-door campaigning, I have a bit of design experience that might be helpful to the cause. Feel free to contact me in that regards.
