The bad news is that they don’t let you go armed. They don’t even let you carry a pocket knife -- although they did let me check it at the front gate so I didn’t have to go back to the car. (Well that, and the fact that none of the roller coasters that SD could ride had enough room for my knees.)
SD wanted to wear matching shirts, and while I’ve always secretly laughed at families that do that, I will admit that there are some distinct advantages. The people running the rides can tell which kid you belong to. If, heaven forbid, you were to get separated, you can point to yourself and say “she was wearing a shirt like this!” But best of all, if you choose wisely, you can influence how you are perceived. Because nothing says “I’m not a victim, nor am I a threat -- unless you mess with me first” like matching Kalishnikitty shirts.
