I did go a "stage manager party" once to try to meet more SMs and I didn't like the vibe...but I was also recovering from the flu at the time, so I'd be willing to give it a go again.
There is often a very cold, vicious, -deleted- attitude when there is a whole flock of us together. I find meeting one on one with another Stage Manager is often better. But even then, there is a lot of name dropping, project hyping, breast beating going on.
It's just interesting to note - as I now live in a city with a HELL OF A LOT of stage managers.
This was definitely my experience at one of 2 SM meetups I went to as well. I wasn't looking to compete, I really truly just wanted to meet people who did what I did! I didn't want to steal jobs, I wanted to LEARN from the people who had been in the city longer than I had (I had only lived in NYC a few months at this point), but there was so much posturing and standoffishness that is was very uncomfortable for me.
The 2nd meetup was much more friendly and low-key. We met at a Starbucks in Astor Place and just hung out. Great, friendly SMs.
Interestingly enough though, the bulk of my close friends here are stage managers. There has never been any animosity between us that I can tell, and we're pretty open with each other! We pass jobs, we cover for one another if someone needs a sub. We are friends first and foremost, and the best part is that we do the same job so we have a great support system of people who truly understand what you go through on a daily basis.
I would love to meet more NYC based SMs who are interested in knowing other stage managers. Even though there are so many of us, we really can be quite isolated in our work, and I think it would be great to have 'real life' people to connect with the same way we do on here.
