Another Pasadena flyover

I missed it, but a B-2 stealth bomber flew over Pasadena yesterday around 2:15 p.m. I think I heard it, but was too lazy to go outside and check it out. Or maybe that was just some other sound- I would think a stealth bomber is supposed to be pretty quiet, though apparently it was flying pretty low. Pictures can be found here.

So again we see high-priced military jets in the sky and have no idea why (remember this?).... it is a little strange that the military never tells us anything about it.
