Here’s a bit of interstate trivia: Did you know major interstate routes are organized by odd and even numbers directionally? So, routes with odd numbers run north and south, while even numbers run east and west.
For example, I-90 starts in Seattle, WA, runs west to east, and ends in Boston, or vice versa, if you choose. This freeway is also America’s longest interstate highway (3,020 miles), which is why so many traveling military families are familiar with its path.
Who has made the trip between Joint Base Lewis McChord and Hanscom AFB? If a PCS along I-90 from Seattle to Boston is your final destination, take a look at some fun and entertaining options on the way. But don’t forget to consider the time of year you travel, especially during the winter. Prepare your car and family for windy, snowy, and frigid weather during the cold months. Even in the summer, you should have jackets and pants on hand when the temperatures dip on windy days along the plains or at higher altitudes.
If your journey starts in Seattle, you’ve undoubtedly spent time exploring the region, so look eastward for new adventures.

Skiing is everything in Coeur d’Alene during winter, so pack your gear if you make the trip during ski season.
