I didn't really start this thread as a survey and these numbers can be skewed by so many factors so this is in no way conclusive. Although I might take your advice mcjnic and do some real research.
Based on the responders who included ages..
age........drummers responding
....- 19....2
20 - 29....5
30 - 39....7
40 - 49....9
50 - 59....16
60 - 69....3
70 +........2
obviously not scientific, but may hint at an indication that many of us are late '40s or '50s so if this is true, does it have an impact on the drums we value or collect?
