I visited JH for the third straight year this year, and along Tarzanman's excellent insight, here are my rambling thoughts:
- The Best Western is a little less than a mile from Snow King, so you're looking at about a 20 minute walk with all your gear. If you take the "Town Shuttle" START bus (startbus.com), which is free, you're looking at roughly 22 minutes, so I'd hop on the bus. Other routes, including the one to Teton Village, are $3 each way.
- Directly across from your hotel is a great sports bar called Sidewinders. They have about 40 big screen TVs including a huge projection screen in the main dining room. Definitely check out the "S" stuffed pretzel appetizer...For other nightlife in town you're best options are the Silver Dollar Bar at the Wort Hotel, the Cadillac Lounge and the Million Dollar Cowboy Bar (all about a mile from your hotel. There's another place called the Tavern in the Square, but a buddy of mine who lives out there says that's the place to go if you're looking to get into a bar fight. Keep in mind that they have taxis in town that have a standard in town rate of $10, so you can get around town pretty easily, even without the shuttle.
- As for the mountain, if there's not going to be any fresh snow, I recommend doing a couple laps on the Apres Vous lift to get the legs going, then working your way across toward the Gondola/tram. If the gondola and tram lines are really long (I don't think I ever waited more than three boxes, about 30 minutes, for the tram in the last three years, though), take one ride up the tram, peek (or drop) into Corbet's, then make your way down Rendezvous Bowl and stay mid-mountain on the Sublette, Thunder and Marmot chairs to access most of the sickest terrain there (gotta try Alta Chutes, Paintbrush and Tower Three Chute if they're open, and the Expert and Lower Expert Chutes are great) and to avoid the biggest crowds. Off of the Sublette chair, you can take a traverse around the corner and drop into Tensleep Bowl, which is directly below the runout of Corbet's Couloir. Pretty cool views from below if you're a pussy like me and didn't do it (closed this year, but I wimped out hard last year!) Another cool area, if it's not too bumped up, is North Hoback. It's basically 2100 vertical feet of leg burning torture, but if the snow is soft it's really fun. There's some great stuff off the Casper lift, too (Moran Face, Moran Woods, Jackson Face, etc.), but those weren't open when I went this year.
- Take Tarzanman's advice and check the conditions on the Headwall, Casper Bowl and the Crags, which some locals call "Marioland" cuz of all the snow mushrooms (pillows) after a fresh storm; if the snow's good, it's well worth the hike. There are two ways to get there...one is via the "white spider," a nasty bootpack directly behind the gonola restaurant, and the other is via "Pepi's Bench," which requires you to take that traverse into Tensleep. From there, stay high, keep your speed and try to make it to the entrance. You'll see the people heading there....
The key with JHMR, and any mountain, really, is to stay on the north-facing slopes. they don't get as much sun, so the snow is likely to stay chalky and fun, rather than sun-crusted and awful.
- After a hard day on the slopes, grab a beer at the Mangy Moose, Nick Wilson's or the Village Cafe....
- one anecdote: my buddy out there says he hears people all the time say how they've done black and double black trails at other places and that they'll have no problems at JHMR, and for some people that's true...his response is to ask them if they've ever felt the sensation of shitting their pants. Some of their Blue trails are steep enough to slide and on one they have to hook the grooming maching to a cable in the mountain and use a winch to get it up the slope (Laramie Bowl). And there are some places you can get cliffed out if you take a wrong turn, so be careful!
Hope this helps! I'm sure I forgot some things, so let me know if you'd like any additional info.
By the way...my avatar photo is me nearly passed out after climbing up the White Spider last year!
