hi sweetp2u...that is difficult...i've moved around a bit so I can understand...if you would like to do something with neighbors, you could invite them over for tea or cake...however, you mentioned that they are elderly so you might want some different ideas.
sandie's idea about joining a church group is good. Another thing I would suggest since you live in Gettysburg is to volunteer at the civil war battlefield center...you would probably meet a lot of locals and out-of-towners there...and learn alot about us history
Other things I was thinking about when I read your email were...
-join a local gym...you can take classes and meet some cool people that way
-see if your local newspaper, library, etc. has a book club...and you can join one...
-Gettysburg has a pretty good college...I'm sure that some people take evening classes...you might want to look into some of those.
-another good way to meet people is by getting a dog and walking it at a park or in the neighborhood...you'd be surprised how many people you meet that way!
Good luck...I'm sure things will get easier soon!!
