I live right outside "The Burg" (hehe--Harrisburg). It's not exactly the MOST forward area, but it's decent. You should have no problem eating veg*n meals here. I'd reccommend Passage to India, which has a lot of vegetarian stuff. It has indian food (duh). Also, there's a vegetarian restaurant called Avatars open occasionally for lunch in Mechanicsburg, I think. I've never eaten there but I hear it's nice. I would call ahead to make sure they're open and there are seats. (I put in that entry for Genesee t happycow.net by the way, it's a cute little HFS with friendly staff and a homey feel). There's also a good HFS called the Healthy Grocer on Trindle Road on the west shore of the Harrisburg area(which isn't really Harrisburg). It has a lot of stuff. It's pretty big, and they have fresh soups and sandiwches and salads and side dishes and baked goods, and a LOT of it is vegan--and REALLY tasty. It's got nearly anything you could want, I find.
You'll want to look in the phone book when you get here--a lot of the restaurants in the menu section of the yellow book have vegetarian offerings, and not crappy stuff either.
That's about all I can think of to say. Oh yeah, and the Harrisburg area has its own vegetarian group--which I haven't joined yet--called Green Street Vegetarian. They might be able to give you some info if you contact them. Their website is

If you have any more questions, you can just send me an email at vegancherrypie at hotmail dot com (except don't spell out at and dot, I just put it like that so those evil scanner things don't pick it up and send it to spammers). I'll be more than happy to help you!
