Heck, I don't know that much about Everett, Washington,
But Ligonier certainly possesses all the qualities that make it worthy of domestic tourism and a deep appreciation of American culture and history. The kids will learn a lot more than spending a week at Disneyweird.
What do you have in Everett besides a sunny day?
The other poster is right. A sunny day in Everett is big news. But Everett is also the locale of one of the Navy's newest Home Ports, home of one of our air craft carriers.
Everett is the county seat of Snohomish County (try to say Snohomish three times fast.) Actually, Everett is the Snohomish County seat, instead of the charming town of Snohomish, because the early pioneers captured the county records in the middle of the night and took them to Everett and refused to bring them back.
Everett is also the home of Scott paper, Fluke Instruments, and Weyerhauser Lumber, as well as a great little microbrewery and pub named Scuttlebutt's (owned by a friend of mine.)
I used to live near there, but that is all I remember off the top of my head. There is also a NFL quarterback named Chris (something) who graduated from Everett High in 1983 who has had quite a career. And never forget the late Senator Henry 'Scoop' Jackson, Everett's most famous citizen of the 20th Century.
