Ongoing mystery

I do a lot of birding along Highway 118 north of Alpine. It never fails that a caravan of mobile homes comes down the highway toward Alpine while I'm birding. So, since my birding lasts an average of an hour each visit, that means every hour mobile homes come through Alpine and head east from there. Where they go is a big mystery to me. This has been going on for years. That's thousands of mobile homes. During today's hour of birding the caravan consisted of 8.

I used a series of still images so I wouldn't have to deal with trying YouTube. My grandson is a computer technician. He says my computer is worn out and I need a new one. Going to do it.
