Where is 100 milehouse? I'm a Spokanite too. Retired from USAF at Fairchild back in 2005. Leaving on March 1st for a month long trip to Mississippi, Texas and back. I have an app on my android that shows all the Walmart's along the route and those that allow overnight RVing. The app is called Walmart ONP if you're interested. It good map (Satellite or Map)view with locations and RVer input from previous stops. There's another one called Rest Stops that works the same as well as RV Dumps. All 3 apps are from "Allstays". Hope this info helps a little.
