If you're moving to Gettysburg, depending on where you're from in California, you might be in for a shock. Downtown gettysburg is touristy, and nice, but the areas where people live...it's very "rural" and the people aren't always the nicest. I moved from Maryland to PA and stopped at a gas station after I got my license and realized it's exactly like my home town, just an hour away. Property in Adams county can be cheap, but check on the school system in the area. I'd also consider moving to certain parts of York county for the schools there. I live in Hanover and it's only 30-35 minutes from Gettysburg. Littlestown is okay if you stay outside of downtown, but the state police have a habit of camping out in the downtown area and pulling people over for suspected DUI's, and then taking you into the hospital to get your blood drawn even if you pass a field sobriety test because your "eyes dialated funny", so beware of that.

Your cars will rust faster if you don't wash them weekly with the road salt they put on the ground. Vehicle inspection can either be painless, or a pain in the ass depending on the shops you go to, so do your research and find a good one that wont rip you off and take you for a ride. Snow tires are definitely helpful depending on the type of car you have.

It gets super cold here, I'm not sure what you're used to, but during January and February we will have days/weeks where it wont go above the teens, and nights will be single digits. If you have an older home, it's VERY expensive to keep it heated. A lot of homes use heating oil which is non-taxed off-road diesel, last I bought some it was $4.89 a gallon. A second common way to heat the home is with propane, which is also expensive, so keep that in mind.

I will say I've lived here for 6 years and I love it, I have no intention of ever moving, but wow I need to do some upgraded to the house, because the winters are pretty brutal on keeping it warm.
