I haven't posted for a while (more into streetlights now) but I passed through West Covina on the way to San Gabriel this weekend. I noticed the landmark Thunderbolt, which stood at the corner of E. Garvey Ave S and Lark Ellen Ave and is also visible from the 10 freeway, had it's head (rotator, chopper, and horn) removed recently; likely due to an ongoing construction/widening project on the nearby freeway. The pole with the blower are still there.
