Trying to narrow down some activities for a family trip. It looks like there might be 20 of us or so with a pretty wide range of ages. It looks like if you come to Jackson, doing a white water trip is pretty popular. I am not worried about our kids, but is this an activity that people in there 50s and 60s can do too? There seem to be a few different companies, is there a company that someone would recommend for our group? We are looking at coming at the beginning of July.
