I concede that I lumped both flying and building as a Hobby and not as a Sport and a Hobby. I tend to think of the use of leisure time for pursuits such as RC a Hobby. Your definition is certainly more precise. On the rest I think we just need to agree to disagree. You believe "ARFs are killing the hobby". I believe it is the age of "instant gratification", X-Box, Internet, etc that are killing building hobby and not the ARFs. I think ARFs are just the commercial response to the decline in building.
On a happier note it was a beautiful day to fly in South Texas.
