Went to Pottercon Detroit yesterday (highly recommend going to one if you're an adult Harry Potter fan- they're 21+ events since they serve alcohol), and I bought a couple of new bracelets:
The bottom is my Hufflepuff bracelet (#badgerpride)
The top is also HP related... but I also kind of bought it because it's part of my favorite Buffy the Vampire quote ("You still my girl?" "Always")
Also got a Constant Vigilance tank top and a Hufflepuff tumbler.
The people running Pottercon are taking it to various cities around the country on what seems to be an almost weekly basis. I think there are a couple things they could probably figure out better (3 food trucks for 5000 people... not the best scenario, ditto with very few bathrooms), but my friends and I all had a lot of fun.
