To make Steve's quote my own.
I was given a couple quick lessons, once, with a welder. I have had several things welded over the years, and know it is a good skill to have. With my unwanted overtime the last few years, when I came on a deal on a new welder (sold as used with all the accessories for the cost of just the welder), I jumped. There are local classes at a community college and I am trying to adjust my schedule so next spring I will take it. This isn't a work skill, but one you can take into many jobs and I would rather have some training, then just waste money on practice, with no foundation.
We also have adult education, but it is VERY limited and I haven't seen any type of classes I want. (mostly things like English as a second language, basic computer use for seniors, how to use Word, etc) To get stuff I would be interested in, I would have to teach it (those who can't, teach).
