I've been through Yuma twice. I was greatly impressed with how little there was to see. I believe the biggest attraction was some sort of casino and the 7-11 which was humming.
The Yuma territorial prison is very nice and if you are willing to drive a bit off-road the Castle Dome ghost town is pretty amazing actually. Their "restaurant row" down-town is also surprisingly decent for such a small town in the middle of the desert. I also found one my favorite Rolls Royces in Yuma.
Yuma's population is about 50, what did you expect. In 1966 I visited my great-grandmother there. In 1990 the camper van blew a tire in the desert, so I drove on a spare tire, a couple hundred harrowing miles to Yuma. I remember that it has a gas station that patches flats. You can visit that. Tell them I sent you, I'll get a free windshield wash.
First Mercedes, then Porsche and now Rolls Royce make a car that lowers their reputations ever downward.
My son may have been conceived in that camper van...didn't happen in the prison, though...he was born about 9 months after our Alcatraz tour...
There's a new article today on BBC, with big pictures of the homeless in Portland. https://www.bbc.com/news/world-us-canada-45442596
