Looking for something to this Winter without having to renew your passport or spend a bundle of money? Then GORP.com has some suggestions for you with this list of ten adventures that don't require a passport.
You'll find some great suggestions on the list, such as Dog Sledding near Minnesota's Boundary Waters, taking a Cycling Trip to wine country in California, or venturing to Yosemite during the Winter months when it's much calmer, and solitude can be found everywhere. Sounds great to me!
