was it hard to get used to a different ride, or just planting into a seat and go? Did you guys all bring your own gear or did they supply that as well? did that include beacons?
It was relatively easy to adjust to the longer track for trail riding - you just have to go a lot slower. At 60 mph, I thought I was going to lose it. The long track really shimmys. It took more effort to learn how to handle the sled in deep snow or on steep grades. You get the hang of it and a good guide can help you a lot. Some things seem counter-intuitive and take practice, like side-hilling. It was a lot of fun and the ability to float through powder at the "top of the world" was spectacular.
We brought our own gear - which I would highly suggest. Your trail riding gear might be a little heavy, but you can strap a backpack to your sled with bungy cords to store any layers you take off during the day. You will defintely be working harder (and sweating more) than you're used to. The rental clothing is lame and their helmets are next to useless (we saw several groups "suiting up" at the rental shop).
As for beacons, at the risk of taking hits from every boondocker on this site, there are two schools of thought. Each one is valid. On the one hand, if you're going to use an avalanche beacon, you really need proper training in avalanche response. I'm not talking about some lame one or two hour session. Everyone who uses a beacon becomes a first responder. On the other hand, if you follow a guide who is committed to avoiding areas where there is a significant risk of avalanche, you won't need a beacon. Our guide was one of the most highly regarded backcountry guides operating out of Jackson. Everyone knew him. Watching him ride was as much fun as riding ourselves. His philosophy was simple. He'll study the terrain and the conditions, the looks of the cornices, the "feel" of the snow setting up, the exposure of the "faces", etc... and he'll keep us out of danger. Lets face it, the guide has your life in his hands in numerous ways - including the way he deals with avy risks. On several ascents into some fresh-looking bowls, our guide turned us around and headed back down, explaining that the avy risk was too high. You can certainly rent beacons, they don't cost a lot. But I thinks its a bad deal to have one on your body without knowing (really knowing) how to respond to others who are trapped in an avalanche. [Let the bashing begin .. I won't respond.]
