I think many of the CO's are sincere, and I think some see it as a racket. It would be tough though, traveling almost all the time, staying at strangers houses. I HATE living and shaving out of a toliet kit. If you or your wife were loud when ya did the dew...well, you're at someone elses house...and that someone else is washing the sheets...so ya gotta be careful. Different style of food every week...and not everyone is a good cook.
Plus side, people sucking up...the envelope passed to ya at most congregations with some cash. It wouldn't be a bad life if you had an income from an investment or retirment check or something.
