Will have a day to spend in Grand Teton Nationl Park and Jackson, and looking for how to spend the day. On this same day, I also want to take the Jackson Tram. Note: I do plan to do a scenic rafting trip on the Snake River in GTNP, but that's not till the next day, and after, going on up to Yellowstone. So, on my day in Jackson and GTNP, what's a good way to spend the day, what to see, do, no miss? Thanks!
