Yes that's right. There's a signing on Saturday I am trying to get to (if I can make it on time with my train) and a Heroes event on Sunday where they'll air the first three eps in theatre with attendance and meet and greet with zach, tim kring and jeph loeb.

You're lucky you tracked down the agency info! I tried finding it, but haven't had any luck thus far. Sending him a letter is cool, usually agencies fwd fanletters (as long as it are hundred a day, ha!) I am sure he appreciates fans telling him how amazingly hot talented he is ^_^
