I visited your site; thought your letter to the Community Board was well thought out. I have a suggestion which may already have occured to you. Have you thought about  inviting the board to the TA et al. Livable Streets exhibit at the Conde-Nast Building? It's such a smart, thoughtful exhibit about the role of cars, bikes and walkers that board members might well get a kick out of it.
A couple of them came to the exhibit at the Urban Center back in March I believe. But that's a good idea to formally invite them and I can add the City Councilmembers from the area.

It is a good exhibit. I do believe that many of them support congestion pricing.
