Non-faith based ways to volunteer around the community?

I'm a veteran going to college on my GI Bill. I don't have any friends or family in the area (originally from Louisiana) and have no real need for a job thanks to the GI Bill paying my rent and such, so I'd like to volunteer somewhere two nights a week to help out, give back, and give me something to do.

and just to head off the inevitable reddit comments, I'd just prefer to volunteer for things not based in a church, but if I can't find anything I'll volunteer at a church before I don't volunteer at all.
