I'm back... from the conference with too much swag. (I tried to avoid some of it, but failed miserably!) The most unusual item was an absorbent cup holder stone. Apparently, you put it in the bottom of your car cup holder and it takes away the moisture from drinks. We'll see how it works!
Another company gave me socks with their logo. They will probably go like the company T-shirts that I received... become wear for bumming around home in.
You might think that the screwdriver set might have won, but this actually useful because you can use it for repairing dance shoes.
Some of the companies were providing samples of their goods, which would be strange give-aways, but being that they were not logo-ed out, I don't think they count. (A set of pillow cases. Clip-on rhinestone earrings.)
I just went through my collection of cloth bags and tossed many prior to attending this. Don't worry, new replacements came home with me! And of course, many new pens, highlighters, and notepads were acquired.
