In the past, I've taken continuing education courses in AutoCAD and Visual Basic at the local community college. Check your state rules carefully, stuff like that is allowed in some states, not in others.
The best technical stuff I've seen was put on by ASCE or ASME (the ACSE 7 Wind Design was excellent, I thought). Occasionally, I'll run across seminars in my field of work that are actually useful in addition to filling the time.
I've done one or two Red Vector courses that took about half the time they were supposed to, which is not a good situation.
I've taken ethics classes through the Texas Tech program and also the NM SPE had some video courses.
