I can't ever remeber anything other than JW business occurring in a KH. It would have been strictly forbidden anywhere I was associated. Not even a picnic table was allowed on the site. Dubland is terrified of lawsuits, so they would never "expose" themselves to the possibility of some thing happening during some pleasurable event.
Got to attend a few family nights over the years, they gradually became boasting sessions with little to enjoy from our perspective.
At one time branch dedications included performances of local music, etc. Heard that Ted "the boss" Jaracz was absolutely livid after a visit somewhere, and they put a stop of such "worldy" displays.
