While in Pendleton, OR, we stayed at the Wild Horse Casino and RV Resort. It's an ok park. There are no pesky over hanging trees to interfere with the satellite.
We are on a 50 amp pull through site. It's level enough that we did not use the HWH leveling system. It's not perfectly level, but it's tolerable. One knock on the site is how far back the sewer is. We did not want to unhook the truck so the RV is forward in the site; we would need more sewer hose than we own to be able to set a sewer.
Power is good, water pressure is good. Verizon 4G is weak. Loading anything with a lot of graphics is like watching paint dry. Interior streets and sites are asphalt. No data on restrooms or laundry facilities.
The tall building in the way back center of the picture is the casino. They do run a shuttle if you want to go there and leave the driving to someone else.
This is an ok place to stay. There's not a lot to choose from in Pendleton.
