Anyhoo, the convention is cool (although I always get nervous prior to business-related travel). It is enormous: 500 booths and takes up the entire area of the Washington DC convention center. It lasts for 3 days every year at the beginning of October and is the largest gathering of defense contractors and military personnel in the world. Because of my job in the Wonderful World of Defense Contracting, I should really be there every year. Ultimately, we should exhibit there, but I don't think I'll ever get them past the "Oh my GOD that's expensive" scenario.
I printed out the list of activities schedule and it is 24 pages long. The list of exhibitors is something like 15 pages long.
Several years ago, the Washington Post, ran an article about the convention and provided a map to the booths that had the best marketing give-aways. The Consul to the US Embassy along with one of the local AUSA guys went to the convention and did the treasure hunt. I wish I could get my hands on another map. The give-aways that I got were pretty standard except for some military type video games where you shoot the crap out of people in different terrain (ok, not so different from most of the video games available commercially, but still). I also got goggle wipes, a tube of goo that will keep your gun from jamming in the sand, a little toy eagle, a whole lotta pens, some key rings, and a few tote bags. Yeah, basically junk, but free junk.
