David,
Yes, I think trying something and judging that it might have a place on 1-3% of golf courses (I know I said 5-10% earlier, but probably on the high side of expectations) is better than asking random people who don't play golf, or posting crazily exaggerated scenarios, is 10X more reasonable track in forming an opinion. And, as near as I can tell, no one on this thread other than me has actually tried playing such a course. Nor have they seen such a course that gets reasonable play.
Brent, yours is obviously one of the over wrought scenarios. That said, if one challenge course full of golfers isn't some evidence of its appeal, I don't know what is. But, I do agree that its not anything guaranteed for success, or something you just change all of golf for, which is what some surmise. And, someone needs to invest their money. I guess as far as "official" golfdom goes, it would probably be more attractive if they knew they weren't going to get slapped down silly here, there and everywhere.
And, the Challenge Course at MD (not a pitch and putt, but there you go again, trying to distort the concept) seems like a great place to do such a thing - surrounding residential for built in clientele, takes less land, might attract those middle class gen X who would try it, and on and on and on. Trust me, its not like Obamacare - in this case, if you like your golf course, you really can keep your golf course! No one will be forcing it on you. (Sorry, couldn't resist the comparison....)
I have never really been a par 3 course kind of guy, but this one showed me it has potential if done right. And the alternate to play to big holes was fun. That's really all I can say as fact - I played it, I liked it, and see some potential and hope someone does try it in the right situations. And, I will recommend it if I find a situation I feel is right for the project.
