I was blessed (read: cursed) with a modern orthodox uprbinging in a suburb of NYC. I desperately wanted to get out, so I sought refuge in the south after high school. I went to Louisiana State University for undergrad, and found Baton Rouge to have a small Jewish community. That includes: two reform temples, no JCC, no Chabad, no kosher restaurants, and a mostly defunct Hilel. I taught Hebrew school at one of the temples as a sub occasionally since they got word that I was a fluent Hebrew speaker and graduate of yeshiva. Oy. New Orleans, just an hour down the road, has a much larger Jewish scene, including an Orthodox shul, JCC, day school, two (or more now?) kosher restaurants, conservative temples, and several reform ones, too. Still, as compared to NY, New Orleans didn't compare. But in a good way. It wasn't as suffocating. As a matter of fact, I loved it.
I've been living in Charleston, SC for 3ish years now. Here, there is 1 orthodox shul ( and 1 offshoot, due to disgruntled members), a Chabad, 1 conservative, 1 reform temple, a JCC, a Hillel (at CofC), a k-8 day school, and no restaurants. The community here is very, very small. Don't let any of that fool you. My mother is still adjusting to the fact that only 30 people show up to Saturday morning services. She's used to 300.
But after all, this is the south, not the Jew mecca.
