Have any of you heard of this? I saw it on the Travel Channel last night. It's your typical mud run, but it has a big twist. You wear three red flags around your waist and as you run through the obstacles and the course, there are zombies (in full costume) everywhere, I mean everywhere, trying to grab your flags. If you can make it through the course with at least one flag, you are listed in the results as a survivor; if you can't, you are listed as a zombie. You can see all kinds of them popping up, and You Tube has a lot of video on them, so check those out too. Some are better than others, of course, as usual.
