Brian,
I think we need to cut the APA a little slack. I agree that a national event should strive for the best conditions, but consider the logistics for just a minute.
I'm sure they are on a very tight schedule to get in, get set up, and when it's over, get out. How many tables did they have? How many man hours did it take to get them loaded in and set up? Now, unless someone from the APA was overseeing the set-up, they may not have even been aware of a potential problem until the tables were already in place. How long would it have taken to call the installers, get them back in, and recover all those tables? Diid they even have that kind of time, or would that have caused delays that would have not allowed them to complete the event?
Granted, there was an issue, but as has been noted, this was the first time something like this happened.
IF the APA doesn't take steps to correct the problem for the next event, they would deserve some serious criticism. As for this one, I think there are probably a lot of things that nobody is taking into account as contributing factors.
We have all had things go very wrong and an inopportune time. If we learn from the experience and take corrective action, it's the best we can do. If we let it happen again, we deserve what we get. I think the important question is, "what will the APA do about it?". Let's give them a chance.
