At about 3:30AM this morning my backyard was lit up like a Christmas tree by repeated sparks coming from my neighbors tree. Both Tiff and I woke up to the sound of arcing pops and the flashing of sparks. I caught a glimpse of the tree as it flashed for about 10 seconds after I woke. I went outside (as Tiffany stayed inside and said ‘be careful’) to take a closer look. While outside the fire department arrived at my nieghbors house. I walked over and explained what had happened. They came over to my yard and inspected the wires. Nothing suspicous. They called PG&E to report the incident and say someone will be sent out.
I think some squirells have eaten through the wires which cross a tall tree.
