Dave, I know what you are going through. I just went 6 months without working and it rots. I had many thoughts of doing something else over that time period but ended up going back to what I know. Hard choices when ya get up past the age of 40. A good choice might be like Daryl suggested. Supervisory role in your field. Taking a few night courses in business management might help in thie endeavor too.
My dream job, maybe something like Charlie Moore. Get to fish and get paid for it.
