Thread: Yellowstone

So we decided we are going to Yellowstone this summer, we have booked our rooms and are going to spend 4 days there. I haven't been there since I was about 14 so tell me what we should check out in each area. We are staying in the geyser basin the first night, the Canyon area the next two nights and then back at the West entrance the last night. I figured that would give us 4 days to do the loop and we will have a chance to check out most everything we want to see. One thing the wife wants to do for sure is horseback riding and I will probably get the river rafting addon, anyone had any experience with any of the companies there?
