A little different suggestion from a SLIC first-timer (actually first cartridge show period!). Not having a lot of extra vacation time I flew to St Louis. It was very easy to get to the hotel and nice having everything in one place. Great way to meet all the people I have corresponded with via email. The cartridges were simply OVERWHELMING! It is an event and I recommend it to all collectors. The only concern I had was how would I get my stuff home. There are of course several options. Mine was come prepared with packing materials and the name of a friend who drove out and would ship back my new treasures.
Perhaps a packaging/shipping option could be offered/coordinated and advertised for the show. It would definitely be a convenience for those of us who fly in. Perhaps it may encourage more fence-sitters to come out and take a look.
As for me, I am hooked and will be there again next year!
