First of all I want to say thank you to the people who put together this events calendar (google account needed to view) for town halls, without which I never would have found this. The closest events to where I live in the next few days are those being held by Scott Murphy (D-NY) in the Albany area. When I googled his name and "town hall", I found a "we surround them" type group that intends to show up at his event on Saturday.
Here is their yahoo group. They appear to have about 25 people going from their group alone, which seems like rather a lot to me.
The town meeting is listed as happening at 11 o'clock on August 8th, at
Golden Harvest Farms
3074 US Route 9
Valatie, NY
Here is the link to Congressman Murphy's site for anyone who can go and wishes to confirm time and date. Anyone in the area on Saturday, please consider making your presence felt, so that the lunatic fringe does not have the floor to themselves.
