Of course, many events purposefully play it safe for health and legal reasons - but I'm sure there must be some out there that go whole hog! There was one place with a "Mud Bowl" that would get churned up and thicken throughout the day into oatmeal consistency
Unfortunately it seems they are under new management and we may have missed our chance on that one
If anyone has any experience with mud runs that feature the kind of excellent mud we all love, please share!
