I noticed a lot of states closing old outdated rest area's and opening new modern staffed facilities. Oklahoma has a nice new facility at the border on I-135 South. They closed the one on the opposite side. At the Southern border they closed the one before heading into Texas. This eliminated duplication and cost savings.
Kansas has some nice ones and some old outdated ones that need replaced. Kansas has closed most on secondary roads, most were glorified outhouses.
Will agree that Minnesota has some very nice facilities.
The rest area's reflect the image of the state to motorists traveling through.
