Dave, did they have both the main hall & Minette halls open??? It is mostly used for agricultural events, so the smell is kinda mandatory...
There are usually a couple guys with just magazines [ammunition type] as well as a couple with just magazines [book type] and books...Did you hit them up for anything???
I always take notes & pick up cards or ask where they are & the shop name...Also write down the table location (numbers hanging from ceiling)...
There's usually a guy near the exit with Pakistani/Khyber Pass junk, for cheap...I try to get something for my trouble even if i don't find anything interesting...Last time it was Pak daggers, $17 each, copies of SS & Luftwaffe daggers...Cheap knockoffs but for $17, who cares???
