Several years ago (around 15 or so) I was on vacation at a small resort in Georgia (Little St. Simon's Island). This place has family-style dining, and since the maximum capacity is 24 guests (and there are usually only around 8-10 at any given time).
After a few meals with this one couple, we learned that their daughter was married to Jon Bon Jovi, so we pressed for all the gory details. Much to my surprise, we were told that the backroom setup (and life in general) at concerts was like a health-food nut's paradise... fruits, juices, health food... not a drop of alcohol or drugs at all in their lives.
Not to burst the bubble but lots of health food people smoke weed as in this case I hear.
