We had some rare east northeast winds in the bay area today, requiring a few landings on the 1's. However, the winds switched to the east before long, which is much more common. I caught the tower feed just in time to hear the FAA mobile vehicles inspecting runways 10L and R before they switched. They seem to switch to those runways for landing (the 10's and the 1's) as a last resort, only if several missed approaches have occurred. All of these runways are visual without any type of ILS system. In fact, despite some east winds, they are already back to using the 28's today, last I checked.
