I've only been through here once or twice, but the "S of Death" does seem like a very poorly designed piece of trail, especially with the off-camber turns. I can totally see that being a VERY easy place to go down, especially in the fall when the wet leaves are down. The fact that someone went down there on B.T.W. Day (when there are not copious amounts of rotting foliage on the ground) is either bad luck or further sign that the S is an easy place to go down.
Probably just a fluke/coincidence, but I broke a rear spoke there a couple weeks ago on a weekend "fun" ride which turned out not to be so fun since to hoof it back to Courthouse and take Metro home. My commute to downtown is via MVT from Alex, so reading this makes me thankful that I'm nowhere near the S!
