Answer: TOO MUCH STUFF.
Basically what going to a convention feels like. Nerd flu abounds!
I don’t think I got nerd flu this con. *knock on wood* However, one of my friends did! It’s pretty much inevitable, when you’re surrounded by people where washing hands and taking baths is optional, and people will glomp you (i.e., violently hug you, frequently without your permission).
I did get much cooler stuff though, although not nearly as much as I usually do. I was somewhat hampered by the knowledge I was flying back, so nothing that I wouldn’t be able to fit in my already crowded suitcase.
