Bet I was at the same show.
With there being only one show in the metro yesterday, I'm sure we were at the same show. I took my 7 yo son for his first show.
Can't answer the OPs questions. Just wanted to chime in on wow, yeah, the prices. $40 mags, black rifles $1,700 and up, and all that.
Speaking of all the deaths and mayhem at the show, for the first time I was concerned about all the knives. Being 7, he wanted to finger everything, even though we had a good talk beforehand about how he won't be allowed to handle the guns. I should have had the opposite conversation - handle all the guns you want, just don't touch the knives.
The guns are all harmless, what with the zip tied actions, many roped together through the trigger guards, etc. Lots of sharp knives all loose and within arms reach. He was still really well behaved and respectful. Made for a proud dad.
Then, when we got home, after seeing all those beautiful untouchable weapons, I had to get out my sig and let him handle it for a bit to get it out of his system.
