>>but still will never understand the number of posts that we see relating to "Hard Rock" in a hobby that for the most part, I Trust, consists of mature adults.
I think you are giving away your age here. While generation gap may be part of the issue, you refer to this music as something for kids as opposed to mature adults. I am 33 years old, and do not primarily listen to Rock, however many of the musicians that the Hard Rock features I view as contemporary to my generation. Actually a lot of it I consider to be old foggey music (Rolling Stones, Aerosmith) because these guys were around before I was listening to music.
Sure there was a day when Rock music was the province of teenagers, but those days passed long ago.
