College classes have gotten almost prohibitively expensive, in my opinion, but our local university allows those 65 to audit at no charge. Well, not 65 yet. but the public library has a very nice selection of computer classes FREE! As well as book lectures and various film series, etc. The classes tend to be one day workshops or evening events, but still helpful. There could be no question about attending these things, I wouldn't think. Of course, I don't know if all libraries do this...
