Iirc, somebody here went last year and said it's basically all the junk from the 1500, but no guns. I'm currently good on my jerky supply so I won't be going.
I went with my brother in law last year and it was basically a bunch overpriced junk. The experts they had come and speak about water storage, long term food storage etc. were nothing to write home about.
Honestly, you would probably learn more from watching a few episodes of Doomsday Preppers than going to this show.
