Need a new career-What Skills are in demand? (employed, degree, jobs)

[KnoxBrian]

I am currently employed as a manager with a heavy equipment dealership, and while I do feel I have a small amount of job security, the jobs is tedioud and can de dull at times. I went to college for a bachelors in Horticulture with delusions of making a good living in the Landscaping and Nursery Industry. Now that I am older and realize more what I would consider a good living, I realize I made a mistake and need to get my professional life going. I gre up in Tennessee, and up until now always thought $30,000 was a great living. My wife earns a good salary (Pediatrician), and we have no kids, so I feel this is the time to make a change. I want to go back to school, for some type of trade. I never really enjoyed college and found it to be a waste of time and money, even when I did landscaping, I rarely ever used anything I learned in school. I want to enter a skilled trade, either through a trade school or a union, where there is job security, and the potential for a decent wage. Since I have ruled out going for a masters, or another 4 year degree, what are some in demand fields that a 32 year old man can enter and gain success with?

Electrician -Lots of specialties that pay more, and cleaner work than other trades. Can then become an estimator or an inspector if you choose.
Welding - Learn the trade, and then try to become an inspector.
Plumber - Great money, and security, but dirty.
Cost estimator or eventual inspector in anything.

I would go the electrician route, if I wanted a Union trade.
