I've taken many free courses at the Poughkeepsie library. All have been excellent . I took a rug hooking class several years ago and have been enjoying this craft ever since. I credit the library class with opening the world of rug hooking to me. The computer classes are wonderful too. You can't go wrong taking a free class at the library.
Public libraries are one of the greatest of all services of your tax-dollars. They exist strictly for your interests and education. Enjoy them, no matter what your age.
