Packless to Portland
For a “pure” shakedown, we parked our car with our daughter in suburban Seattle, walked to the Amtrak station, and boarded the Cascade train for Portland. The only extra baggage was a shopping bag with zucchini bread for our hosts & our son. The walk was easy with very intermittent light rain and 51F.
Amtrak is comfortable, with leather seats, nice legroom, a chance to stretch, a snack bar with a few tables, seat trays & wi-fi. A TV monitor shows en route progress, with times to the next stop (including warning messages as you approach). This route runs under the new Tacoma Narrows bridge, along Puget Sound, past intermittent forest & farmland, before following the Columbia River to Portland. Much more relaxing than driving.
