I really want to take up MD'ing when I retire. Unfortunately my wife tells me that I do my best to run away from her with different activities as it stands now (probably common theme from guys on this site), so fer now, out of the question.
once you start bringing some good stuff home (silver and rings) she will be sending you out. My wife had a fit when I bought my first MD in the late 70's for $350. I told her I'd pay it off in 3 months and I did with my finds. Like fishing you never know what you'll catch.
