Mark is a generous and caring host, acting as a paternal figure in enabling whatever one's intentions may be in San Jose/Silicon Valley. I was riding my motorcycle for the summer, and Mark, as an avid rider himself, provided space and tools to work on my bike while I was there. I did not assume he would do this, nor did I feel he was obligated to, but his experience and resources proved invaluable time and again. His house is lovely, often filled with vibrant characters that gravitate to Mark's own magnetic personality, and his approach to one's stay is adaptive in his communication style and what sort of experience one seems to be requiring.
