ETS does not show at trade shows. Aeromedix, retailer of the RSK knives, etc., has a booth as EAA AirVenture (Oshkosh), the only show it does, but that's not a viable proposition for holding any non-aviation related event and in any case would be even more difficult and expensive due to the enormity of that event. I do attend various conferences (non-public invited) and shows (SHOT, OR, Blade), but none that would lend themselves to public attendance or, again, they are so large that they would drive the price up, or they monopolize my time. Piggybacking on some other event is certainly a possibility, but nothing currently on the schedule lends itself to that.
