My son goes to college at Penn State, so I looked into this a bit a while ago. My son is not a cold water diver, so he doesn't plan to dive up there any time soon, but I did find some links that might help:
First, since you're in State College temporarily, if your husband is in a visiting role at Penn State he might be interested in their
Scientific Diving Program, which looks pretty cool. To see Penn State faculty involved in that program,
check out this page.
There's also a student scuba group,
Nittany Divers Scuba Club, that has faculty and instructors listed on their page. While it's unclear from their website,
Facebook page, or
Instagram page if they are still active, you could contact them through any of those. Also, they do also have a
scuba links page that lists scuba locations and groups in the area that might be helpful.
There also appears to be a State College scuba club,
Blue Lion Divers, that is not affiliated with the University and has some contact info on their website. They also have a
good list of scuba links for the region and a
Facebook page with some members who might be potential dive buddies.
While some of the websites above may not be so recent, there's
Laurel Divers scuba club in Altoona (not too far from State College) that appears to be very active and looks to have events on their
Event Calendar going on this weekend and the next. They also have a private
Facebook group that shows activity within the last month. Might be worth checking this out first since they have stuff going on this weekend.
