transit worries

When I got back to Manhattan in June, I was a little nervous about whether I still remembered the subway routes I used to take, especially because I was living on the East side, so now I had the 6 only - but midtown, where I worked, was another story. So the 6 took a day or two to get used to, but almost immediately it was like nothing had changed. Except I don't do buses in NY. Subways, sure. But buses, I'm afraid of doing something stupid, like getting on one and ending up in Queens or something. So in the year I lived there before, and all summer, I have not used the bus. Which brings me to this: Chapel Hill tranist. I will be taking a bus this year to school. It seems simple enough, walking up the road to the Southern Village Park and Ride lot, and taking the express bus right to UNC hospitals and then walking to SPH. I don't know why I'm so nervous about this - it's not like Chapel Hill is THAT big that I'll find myself somewhere crazy. But it's something new, something I'm not used to, so I guess it's understandable.
