Dedmiston went and did it this weekend, per his facebook page broke his Tibia Friday in the desert. Get well soon Dave, bummer to get hurt so early in the desert riding season. Guess you'll be driving...
I've done almost the exact same thing. Stepping on the wood in a firepit (while on fire) to show the kids it's not stable. It was but the rock I stepped on coming out broke my ankle. Scared the kids straight though :)
You are not alone and it's not even an unusual event!
