Over spring break my 12-year-old son Leo pushed me to take him on Los Angeles’ longest bike trail: the San Gabriel River Bikeway in East L.A., which runs for nearly 40 miles from the mountains to the Pacific in Seal Beach. The bike trip began pleasantly but rapidly became a tour of Los Angeles homelessness. Along the route, we passed hundreds of encampments, where thousands of homeless people were trying to get by. From what I saw and overheard, many had substance abuse issues, probably connected to the opioid epidemic currently plaguing America. The scope of human capital wreckage dominated my thoughts for days.
