If he's in say, Redmond or Issaquah (especially the latter), where some of the MS campuses are, biking every day all year becomes less viable. There's no way I would ever bike to work in Issaquah even if it was a reasonable distance, because you spend too much of the year getting pounded by rain/snow in cold temperatures, or subject to high winds.

I do agree about Seattle proper, though.

EDIT: For reference, Gates' home is in Medina, WA, near Redmond. It appears to lie pretty close to Lake Washington, so the weather is PROBABLY relatively similar to Seattle, but it might be more unpredictable since it lies further inland...
