I've never experienced single digit weather, let alone anything below zero degrees. Jackson Hole welcomed me with just that and showed me what freezing temperatures can really feel like. Certainly colder than your typical trip to Tahoe, but far more epic.
We started the trip with a snowshoeing expedition up the Teton Mountains, an activity that I completely underestimated in difficulty. Worth mentioning everyone in my group was twice my height -- think baby steps trying to keep up with giants steps! Don't get me wrong, I love winter sports, but I normally imagine myself snowboarding down the slopes not hiking in these conditions with people who are 6 feet tall! I was beyond exhausted.
Overall, even if my tolerance for the cold is low, my desire to go back to Jackson Hole is high. The food is excellent and the views alone are tough to beat. I can already taste my veggie pasta from The Granary and breakfasts from Lotus Cafe. It's a bit of a trek to get there from SF but if you want a true taste of the "West" it's worth the journey. If you need more persuasion, simply go to the Million Dollar Cowboy Bar and find out yourself!
