I think this one will get crossed off my list sooner than later. This summer our very own Grand Rapids is hosting their color run, which I'm sure has been going on for years. I hate running to say the least but I think it would be really fun to run while being painted with powdered colors creating something that is beautiful mess. You can sign up as a group of 4+ and I think it would be a great experience to do with friends. @Sanne1
