Not sure, but I believe his accident happened fairly early in his study of WC/VT before he became a student of WSL. I think I remember hearing that some of his prior instructors and si-hings had a very dismissive attitude toward his efforts and potential after his accident, basically laughing at him ....and that helped motivate him to look for a new instructor. Boy were those guys wrong!!!! Lucky for the rest of us. (Even though I argue with the WSL-PB-WC guys, I think Sifu Bayer is very impressive and has contributed immensely to WC/VT in general).
Now this may just be a myth, but I thought it was a good story. Hopefully LFJ can verify whether or not this has any basis in fact.
