It’s funny, I road-tripped from Seattle the last Jackson Gathering in 2015, and had my car (Subie Forester with snow tires), but there were always other people who wanted to drive their vehicle. Carpooling from town is preferable to driving alone, since the parking near the base is free for carpools. It was convenient to take the bus to Teton Village as well, and I could easily walk around town.
I’m thinking of road tripping again and taking a few extra days, and ski a few places along the way (maybe Silver Mt or Lookout, Lost Trail, Grand Targhee). Might take an extra week and head to SLC and my SO might be able to fly in and join me, visit relatives, road trip back home with a stop at Sun Valley.
