From David Aronson, who also knew the cave-dwelling ultrarunner and one-time mentor of Caballo Blanco:
I met Smitty, mentioned in your book, on Maui back in the early 70’s. He was experimenting with different foot coverings at the time such as duct tape, gauze and Thorlo socks in addition to his barefoot running. I even tried going barefoot, motivated by him, but gave it up after a few too many kiawe thorns in my foot! (Even then I liked running off road if I could.) Anyway, Smitty was a great guy who would always greet you with an open heart. I believe he inspired a lot of people and was quite the character also. Enclosed is an article from the Maui News about his sudden death.
