Heck guys, I have not been to a trade show since I quit running die stamp presses in 1986! I have never gone to a screen printing show, and am looking forward to Long Beach as my first.
As for free, you don't need me to help you in that regard. The show itself has free pre-registration, as Jill linked, and most industry manufacturers and distributors should also have passes or codes, especially as the time approaches.
And for the record Jill, Frogs are amphibians! ;D
