I spent some time scouting for WiFi last year at Oshkosh with my Ipaq
PDA. There were several networks in each of the four conference halls
but none of them were publicly accessible. EAA apparently charges
exhibitors big bucks to access the networks. At the "member center"
there were a couple of rows of PCs set up for public web browsing. I
asked the hostess there about WiFi and she looked at me like I had two
heads.
