Not for Seattle, especially if you have kids! Our cost of living is pretty high and there is a lot of competition. Most of the classes are nights and weekends, and being gone that many nights and weekends gets old fast and can be very disruptive to the family, which if you wanted to do it full time, would require at least a couple nights a week and a fair number of weekends.
Combine it with some other things, and definitely!
