Here is a link to a very sad event that happened to an avid motorcycle rider. He was riding and something that he had packed on the bike (sleeping bag/bedroll) came loose and got caught in his back wheel and he went down. He is in the hospital and he lost a toe on one foot and lost the entire foot on the other leg. They amputated his foot, and then Memorial Day amputated the leg a little higher up so that he has room for a good prosthetic.
He is making updates regularly - but here is a link to the first video after the crash.
