Arlo loved to listen to late-night radio, long after the rest of us had gone to bed. I would get up in the middle of the night, look downstairs, and see a light under his door. He liked to listen to far-off stations, like XERB in Tijuana, Mexico, with Wolfman Jack.
I asked Arlo recently if he really liked listening to Wolfman Jack, and he said: "Not really....it was just the only thing on at that time of the night!" Arlo and I used to put together crystal sets, mostly for the novelty of being able to produce our own radios. They didn't pick up much signal, but they were fun, nonetheless. He also enjoyed messing with electronics, and later became an electrician.
One memory that stands out is when he was about 10, and I asked him to test some Christmas lights for me. When he plugged them in, a huge spray of sparks flew out of the socket, sending my brother reeling back with several loud shrieks.
In spite of that shock, Arlo's interests in electronics and radio continued; as an adult, he was a licensed electrician, and radio host for KMUD radio in Humboldt County, California.
