Meeting/finding friends in Stuttgart...I'm an expat

Hi, I'm also an American living a long time in the Stuttgart area. I'm a performer and have most of my gigs on weekends, so not a great fit to do a lot of things with someone who works during the week. But I am flexible with my time and live pretty central (Stuttgart-West) so a quick get together after your work in town could be possible. Anyway, if you need any advice you can contact me. As far as other Americans in Stuttgart - I don't know many. There are people with the local US Army facilities but they seem to keep mostly to base or keep a very low profile. There are always some American students at University but unless one is a fellow student then one is not likely to meet them - and they usually only stay a year anyway. Otherwise, there are a couple of Irish pubs in Stuttgart that tend to be a meeting place for English speaking expats but mostly for the early to late twenties drinking crowd.
