After finally making it through Montana, we began to travel across Washington. I will say that Washington is much more interesting than Montana. It’s not that Montana is all bad, there is just so much that is the same.
Part way through Washington, we stopped at a lookout point in Gingko Petrified Forest State Park. The views were AMAZING! Be sure to stop by that point along I-90 just before the bridge to cross the Columbia river. There is a nice park with some great plants (and lizards) all around you.
