- When planning your trip, be sure to rent a car as public transit in this region is scarce. If you are flying in to the Tri - Cities and don't plan on leaving, then you can survive on the bus system, but things will be a lot easier with a car.
- Keep in mind that compared to the rest of the US, there can be quite a distance between gas stations in this part of the state - especially if you go off on backroads.
- Roads are often well maintained, but travel by car to Seattle and Portland can get questionable during the winter. The Gorge is prone to Ice Storms, and the passes to Seattle frequently get clogged with Snow that can take road crews days to remove. Chains are required for both routes during snow season.
- As a nice contrast to the rest of the state, roads are often nice and wide. Due to the small and scattered population, congestion is almost nonexistent with the exception of Holidays.
