When I worked at Microsoft, people always asked me if I had ever seen Bill Gates. Yes, he is around campus a lot. Even visitors I had on campus sometimes saw him.
I have a few photos of Gates' house from the outside. When I worked at Microsoft I put these up on my Work page, and had an incredibly number of hits to the page of the photos...in fact around 100,000 a year! So, to keep the "world" happy, I will keep these photos up on the site...in hopes that it will bring me "luck" and cause great escalation to the value of my Microsoft shares! :-)
