I read the column referred to. Can't say much for it ... was it written over the kitchen table by a local?
Nonetheless, the columnist's advice is, IMO, right ... nothing wrong with it unless the practice is leading one of the participants into danger. At that point, maybe you could get together at an ice cream shop.
When I was Scoutmaster and my wife was Assistant (really the one who did most of the work), there were always a few parents who wanted a monthly visit together to the local bar. It gradually seemed to overshadow their real reason (excuse) for being out. Odd how they were, at least half of them, the parents with boys of whom I always said "that kid needs a parent to straighten him out."
