Great Northern Leg 6: Missoula to Seattle

Once you reach Idaho, visit the adorable town of Wallace (used in the film "Dantes Peak"). Here you'll find the strange Oasis Bordello Museum, which is dedicated to the last cathouse in Wallace. It was open until 1988, when a raid forced the prostitutes to abandon the building, leaving it mostly intact. It was later purchased and preserved, so it looks as it did in the 1980s. The mannequins and 80s-tastic decor are pretty kitschy and the whole thing is fascinating, if not a touch bizarre. Once you reach Idaho, plan to spend some time in Wallace. It's an amazing little town that was also the primary filming location for the action film "Dante's Peak." One of the coolest places to visit in town is the Oasis Bordello Museum. This was a working brothel until it was abandoned in 1988, after it was raided by authorities. What makes it such a cool museum attraction today is that it was abandoned so quickly that most of the clothes and furniture was just left after the raid. And it's also rumored to be haunted! People say you can hear the sound of women talking in rooms that are completely empty and often times people also smell pipe smoke or perfume. The museum is open seven days, and admission is only $5.

Then it's onto Crystal Gold Mine in Kellogg. Regardless of what time of year you're road tripping across I-90, this is a fantastic stop. It was a working mine from 1879 until 1881, then it was closed and forgotten until 1991. In 1996 it opened as a historical tourist attraction. You can take an underground tour here, learn all about the late 19th century mining methods and experience what life was like for miners in Silver Valley.

Next, head to Old Mission State Park to see the oldest building in Idaho. The Mission of the Sacred Heart was built in 1850 and is a fantastic place to learn about the history of the area, from its first tribal inhabitants to the Jesuit missionaries that later settled there. There's a visitor center and gift shop onsite, and it's close to the Trail of the Coeur d' Alenes, one of America's most amazing bike trails, in case you've brought your bicycle on your road trip. If you keep going for a few more miles along I-90, you'll reach Coeur d'Alene, Idaho. This Idaho city is filled with natural beauty, which you can experience at Tubbs Hill Nature Park. Enjoy a nice meal and some local beers at Crafted Taphouse and Kitchen, or get the perfect breakfast at The Garnet Cafe. And as for hotels in Coeur d'Alene, spots like the Roosevelt Inn, Coeur d'Alene Resort and the Greenbrier Inn are excellent options.

From twisting roller coasters and gut-wrenching drop rides to bumper cars and train rides, Silverwood Theme Park in Athol, ID is an old-school theme park that definitely brings fun for all ages. Also, they have a waterpark with a lazy river that has a bar right in it!

Locally-sourced gourmet pub grub and loads of beers are two great reasons to grab a bite at Crafted Taphouse and Kitchen in Coeur d'Alene. But you'll definitely want to stay for the turtle races. The prize for betting correctly on the race? $1 beers!
