My husband and I are thinking about visiting Sequoia after our Yosemite trip on our way home to El Paso. As long as we have chains on the tires, is that a decent time of year to go? We're thinking of staying two nights very close to the park. Will that be enough time? Too much time for that time of year? I really don't have a feel for weather conditions in Sequoia that time of year. Are we in for a lot of skiiing/snowshoeing to see the "big" attractions?
