We'll be having our own Tea Party in Richmond on - appropriately enough - Tax Day, 15 April. If you're in the area, c'mon down and be heard!
I know most of us who give a shit about this stuff are actually, you know, gainfully employed and all that so this will take place from 6PM - 8PM so you can participate and still do your part for the GDP.
Details and directions at the link.
Update: The link I posted is to the Richmond Tea Party blog, which still has all the info you need, but here's the link to the official site.
