I'm Midwest boy, turned Silicon Valley engineer, entrepreneur, and venture capitalist. I collect wine, play classical piano, and have been known to take my car to the race track.
I'm not going to cook or hang out in front of the TV. I'd much rather enjoy your city's food, and TV isn't my style. Aside from showering and sleeping, my biggest intrusion will be taking enough table space for my laptop if I need to work (and putting it away when not using it). Also, I won't have guests.
I'm very outgoing and happy to chat with my hosts (or leave them alone if they prefer), but spend most of my time out meeting with people and enjoying your city.
