Alan Pitcairn and William Bay hosted Lightgathering in San Diego in 2019. Alan and Brigit graciously opened their house as the community gathering place. The house also served as the campground for the folks that were willing to rough it.

The big photographic event was a guided tour along the US/Mexico border fence with the US Border Patrol. In San Diego there are 14 miles of border fence that starts at the ocean just south of Imperial Beach, and stretches East towards the desert foothills of Otay.
