The U.S. Department of Agriculture offers classes for working adults through the USDA Grad school, daytime, evening/weekend, and online. The courses range from language classes to photography to computer certification programs. It seems weird that its run by the Dept. of Agriculture but really its run by the Federal Government. Most of the classes are great for working professionals who may want to learn something new one night a week and will give you the opportunity to meet other people your age interested in the same things.
