Lori, I think the plan if someone gets hurt is that we all go back. It kind of sucks. (Been looking forward to this for a long time now, have spent way more money than I ever dreamed I would, etc.) BUT... I can't see any way that some of us would keep going while someone else went back. Or else we'd camp an extra day and see if whoever was hurt recovered enough to keep going (or, alternatively, hike back out). We've already got an extra day built in to just chill at the top, so that gives us just a tiny bit of leeway. The only time we might split up at all is after setting up camp or on that extra day, but in that case, the plan is to always stay in groups if we're going to be leaving camp. I can see my dad possibly going off alone, but I would most definitely not go anywhere by myself (except to the bathroom). My dad has a ton of experience with camping/hiking/nature that I just don't have.
