Ed,
I don't know--partly because I haven't attended any of the big "winter shows" like SHOT or SCI for a while--because I have also been deliberately "semi-retiring" for several years.
Partly this was because I was learning less and less by going to the shows--because of the increasing turn-over among the people at various companies. When I started going to SHOT in 1988, the same people often worked for the same company for not just years but decades. But after around 2000, they tended to last only 2-4 years at most before moving to another company. I suspect this is partly because "electronic communications" have made it far easier for people to switch jobs, since they don't have to physically move, as they did before.
