Opinions on ICAS membership?

Hello everyone:

I'm curious to know if there are any ICAS members here, and if so, what their
opinions of membership are. I currently operate a static-based airshow exhibit
featuring several pioneer-era gliders and flying machines. Since my exhibit
lacks the four main selling points of a normal airshow act (smoke, flames,
noise, and speed), I am especially interested ways to increase my marketing
power and book more shows each year. Would an ICAS membership help in this
respect, and if so, how much?

Thank you,
Harry
