In my state, seniors can take classes at state colleges for free. Easy to sign up, too. You're treated just like any other student.
The downside, as I discovered after signing up, is that I had to pay to park on campus (there is no nearby parking otherwise), at $140/semester. Then there was the cost of a textbook, which in my case was only an online book that cost $120 (no other option, since class assignments were only available via the online book). So not exactly free, but I think I got my money's worth. Having the student ID gave me a bunch of great deals through the bookstore, and saved a ton on various software and other purchases.
