I saw this near me and was wonder if anyone has ever been?  Is it worth it? Do they hand out any free gifts?

I went to the one in Richmond and they didn't hand out anything free but it is totally worth it b/c the LEGO store had all sorts of great deals and retired sets.  My city was the first on the tour so I am not sure if they were just getting rid of stuff but I would assume they have great deals at each of the shows.  I got there late on the first day and most of the deals were gone but I talked with some other brickpickers who go there at opening and dropped a ton of loot on some great deals.  I asked someone who went every day and they said the first day deals were much better than the last day deals.

What retired sets did they have and what were the discounts?

I would love to go to it.  I am assuming I would have to be with the "big" kids though.

What retired sets did they have and what were the discounts?

They had some retired ninjago sets...a few HP sets...  and I am not sure what else. I wasn't really looking for anything else though either.
