My son woke us at 3:00am when there were 4 loud booms and bright flashes of light and firework sounds (but NO FIREWORKS in the sky) like cracking and popping.
Looked like it came from over the 215 fwy at the 210 fwy area. Anyone else see or hear it? We are located near 17th St and Campus Ave. in Upland CA.
Please reply or post if you saw or heard anything. We lost power for 1-2 minutes each time, bedside clock started blinking, so I had to reset it over and over.
