That's exactly why I was wondering about the makeup. You can never be too careful these days. (It's also why I wouldn't even think about bringing prop weapons. Bad idea!)
I was probably only going to do Splitter makeup at most, and maybe contour my face a bit. Zombie would be cool, but like you said, it covers the whole face.
I also just remembered that students from Theatrical Makeup often wear their work around campus with no problems. Even so, I'm still going to bring makeup remover, just in case. ^^;
Thank you for the advice!
