Hi Angi, I'm an ASA alum from Clarion, so I will gather that the situations are similar!
Number one is to make sure you keep the alums involved and up to date on what is happening. If you don't have a website MAKE ONE. I'm assuming from the size of your alum base that your chapter is fairly young, so the majority of alums should have computer access or at least be computer literate. Even if you do have that in place, try to send a physical newsletter at least once a year. And don't just fill it with what you are doing - ask the alums to contribute too.
When alums do come to visit, don't be afraid to loosen up around them once you get to know them! They probably still like to do a lot of the same things you do, so don't think you need to get out the tea set and white gloves just cause they're 10 years older than you.
Does PSS have something set up that you can set up a chapter-based association, rather than the regional type alum chapter? If so, definitely look into it. (Barbara - Shippensburg [like most PA state schools] is basically located in the middle of nowhere and students often leave the area after graduating, so getting a traditional regional alum chapter together - let alone one with enough manpower and money to help the collegians - can be difficult.)
Contacting alums can be frustrating, but you have to not give up. You never know when a "lost sister" will come back into the fold and make a huge difference. Good luck!
