I have just signed up for a class in basic home repair skills, including light repairs on plumbing, electrical, drywall, and carpentry. It meets for 6 two-hour evening sessions in February and March. It is offered through my local community college.
If you haven't checked out what your local community college has to offer, you are missing out. They typically offer a range of "continuing education" courses from one-day to full-semester, including everything from cooking to auto repair to personal finance. Ours even has courses in channeling spiritual energy, stand-up comedy, and installing solar panels. All at extremely reasonable prices. Over the years I have taken weekend and evening courses on High Desert Gardening, Backyard Ponds and Water Gardens, and Digital Photography.
Other sources of interesting and affordable classes and workshops include the public library system, school district, and museums. The local school district teaches an assortment of adult education classes. I took a Broken-Tile Mosaic class from them that was both excellent and a lot of fun. From the Nevada Museum of Art I have taken Japanese Print Making and Pine Needle Basketry. Next Sunday I am signed up for a follow-up workshop on making lids for pine-needle baskets. And, although I have not taken classes from the public library here, I have in the past taken a class on Cooking with Chilies from the Tucson Public Library.
Here's the description of a popular Truckee Meadows Community College course that I may just have to sign up for some spring:
"Wine Country Safari
Explore Napa and Sonoma like you never have before. Each morning take birding and natural history tours of the region's woodlands, lakes and forests where you'll see an enormous variety of birds and wildlife. Then refresh yourself during afternoon wine tastings."
