Cath brought up an East Coast Meet Up to counter the LV meet up.  And it seemed like some had expressed interest:

Okay, I did some very prelim. research on going to see the Angels at Citi Field on June 16, 17, 18 (Fri, Sat, Sun).  They are "normal" game times, but they might change due to Fox and ESPN.  If we want a group, we need at min. 25 people - and a $100 deposit.  Stubhub also has decent seats (all the way up, behind home), 18 together for about $29 (don't know fees) on the 16th.  I don't know how hard walk up seats will be because it is a. the weekend and b. how good will the team be.  

I am not volunteering or asking to be the coordinator.
