There are plenty of good camping options to be found within three or four hours of the metroplex, but few of them offer the kind of scenery, wildlife and rock climbing opportunities you'll find in Western Oklahoma's Wichita Mountains National Wildlife Refuge. With a large herd of bison, the refuge is your best bet in the region for a true, in-the-wild glimpse of the beasts that used to roam this part of the country by the millions. It's also home to more than 240 species of birds, several prairie dog towns and more than 800 head of elk, all of which you might run into as you hike the many miles of nationally recognized hiking trails. So pack a tent, head out for a long weekend and get some fresh air in those lungs, city dweller. And make sure to stop in Meers for the world famous Meersburger—just don't ask for mayo, or they'll call you a sissy. It's Oklahoma, after all.
