Yep I went down in the sand. 1st test Short.

Playing around on some 42 psi Metzler Tourance tires in fairly deep, dry sand. So yep, went down, twisted ankle. There's a picture of the bike down on Instagram.

Even I go down every once in a while in sand.

Edit:
2 days later

Also to note: I was wearing regular, everyday cowboy boots. Not exactly a protective motorcycle boot much less an off-road style protective boot.
There's always the possibility that I would have twisted my ankle just as bad or maybe even worse, but none the less I caught my foot between the top box and the ground which resulted in twisting my ankle pretty badly. Couldn't really walk on it the next morning.
Luckily after Manderjack made me elevate and ice it I can now walk on it the 2nd day.
