Cogdogblog has this great photo about where all conference bags go
SOOOOOOOOOO true. I just got back from SITE and have one more worthless bag and worthless propaganda to trash. They even gave me a water bottle. What is that supposed to be for? Who needs a water bottle? Who needs another bag? The only thing I needed in the bag was the conference proceedings CD. Now that's somewhat more useful.
AECT is the same way. I still have their bag (although I don't really need it). No more! Conference-goers revolt! Demand that they take our hundreds in admissions fee and give us something useful!
