Dave, some of us can not attend a 9 a.m. meeting because of work schedules. Is there a way you could take copies of letters from those who can't be there...either because of work; or because they are not here physically...and present them to the TDC?
When I worked as a lobbyist I would often present my case, and then back it up with a "batch" of letters from others supporting my point of view. It usually had a pretty strong impact. This works even if people have written individually. Presenting the batch of letters/emails to the Chairman and asking that they be entered into the Official Record as well, is a strong visual.
Just a thought....
