A very simple yet fun costume. Even though you're wearing shorts, as long as you're running about and remaining fairly active (which you should, since you're the Scout) you won't notice the weather too much.
However, all the running, screaming and waving a bat about will scare other people. But don't worry too much about that. As long as you're not hitting people with the bat, not screaming too much and if the bat isn't aluminum (aluminum bats are illegal in some states) you should be good.
Updating the costume by re-spray painting the bat, using different shoes and getting baseball socks. The update won't be completely done anytime soon due to lack of funds and since I'm trying to do another cosplay.
No awards, but many people enjoyed it and said that they would have done a Team Fortress 2 costume as well if they knew I was going as the Scout.
