Our first morning in Yellowstone we set up camp. We got the 'bear talk' before we could get our campsite, and I have to admit it made me quite nervous. I was worried each night that a bear would walk through our camp. Luckily, we missed any bear encounters.
Then we headed over to the Old Faithful area to see the pools and geysers. My favorite was the Grand Geyser, which I thought was much cooler than Old Faithful. It doesn't go off quite as often as Old Faithful, but it can be much bigger.
There were a couple of wildfires in Yellowstone while we were there. You can see the smoke behind Old Faithful.
