Gadolhadorah, don’t forget hit men and pig farmers. I wouldn’t be so sure about rodeo cowboys — the Five Towns branch of Bonei Olam is sponsoring a rodeo.
MDs, even if they have time to learn Torah two hours a day, probably don’t have time for the CR, so it’s best to stick to something less demanding like a Fedex driver. It has the added advantage of being able to double park and get away with it.
