What sort of program does the Experimental Aircraft Association have
in place to reduce the death toll resulting from AirVenture
attendance?

Alot of times, these aren't the sort of things EAA can do anything
about. What can EAA do about a stall/spin on short final? That's been
happening since shortly after the Wright Bros, and I suspect it always
will.
You can make all the rules you want, but showing up unprepared is hard
to prevent. Sanction and punish, sure maybe (but very much NOT likely),
but not prevent.

I just don't fathom how you can fly to this without at least reading
the NOTAM...

One other story told by Jay: apparantly they heard two pilots flying
together on the air-air frequency; one was trying to download the NOTAM
onto their PDA, and then trying to read it to the other pilot...?!?!

Oy vay!
