Really not a big deal, considering Washington probably has the most plentiful truck parking of any State in the United States.
Sucks that rather than move the people, they choose to simply shut down the rest areas.
Homeless people are taking up residence everywhere at this point. It's not a big liberal city problem anymore, it is nationwide, rural areas included.
Amarillo, TX: Two rows of Walmart's parking lot is people living in their cars, or permanently parked run-down RV's.
Kingman, AZ: Flying J employee living in a trashed out RV in the truck parking area.
Lowell, AR: This is right by my house. People took up residence at Workmans's Travel Center sometime early in August, or maybe even July. They have been there since. Pisses me off, because they took the shaded end parking spot, which I felt was basically my designated parking spot up until that point. I have been tempted to inquire inside about it, but afraid it might end up being someone the people know. The folks who run Workmans travel centers probably wouldn't say no to anyone in need.
Can't remember the city off the top of my head, but it's on 99 in Cali. There is a Pilot and Love's truck stop, and under the trees at the exit there are multiple tents, and there are people that work at the truck stop fast food places living in them. I literally watched them come out fully dressed and go inside to work.
Just about anywhere you go, you don't have to look too hard to find homeless people living in a parking lot.
