Well, what shall we do ? Do we meet at a hotel ?
Do we want to do something like Jillian's in Boston.
It's on Lansdowne street accross the street from Fenway Park.
They have private rooms there for functions and parties, etc,
(lots of) pool tables, gambling (for fun), darts, videogames, motion movies, dinner, etc. etc.

Sounds like it might be 10 or 20 of us ? plus guests, maybe 50 people ?
I don't know what might be appropriate for an owner's meet itenerary,

Probably a saturday afternon thing would make sense,
It'd still be daytime so people could show off their installs, etc,
There'd be a few hours of entertainment, cocktails, hors d'ouvres, etc.

Then people could have dinner on their own and/or stay in the city for the night, if they want.
OR
We could come up with an itenerary where dinner and hotel accomodations are prepaid.

The former could be arranged for something like $25/person.
The latter could get expensive, especially if it's in the city, but maybe not ?
If it was $150 a person, for dinner and a hotel room, not bad ?

Not too sure how crazy we'd want to go, maybe people could post their feelings ?

Let's hear what you think !
