The Good: Getting a chance to cosplay with my wife and daughter was great and there were a lot of supportive remarks. Picking up a comic I had been after for ages was another high-point. There were so many people who, despite the heat, were being polite and seemed honestly happy to see cosplayers and especially child cosplayers.
The Bad: The heat and the humidity, not to mention the smell of people affected by the heat and humidity, were an issue. It was almost made worse by the fact that there were so many open areas where you suddenly got cold. And the press of people was not easy for someone carrying a sword and shield, especially the number of rude people who would force their way past you and push children out of their way; I have no idea how that Jupiter Ascending cosplayer got through the weekend with her impressive costume.
Hey, I'm a little more than 20 and I'm still getting excited about CMMK 24 already. If it happens in November, expect me to be even more excited.
