It appears from all the posters that the average age of the #3D pilot is around seventeen years old. Most males this age are pursuing the national past time of girl watching.
I have been all this country and parts of Europe and have never whitnessed a gaggle of seventeen year olds at a flying site. The most young pilots I have seen at an informal flying site was no more than three.
Out here on the West Coast the average age would be somewhere between 27 and thirtyfive years of age. If you want to meet all the young people you need to get into R/C cars and trucks.
