We went to Yellowstone and spent too much time looking at Elk, Bison, etc. and got to Old Faithful just after it "went off". Had to wait an hour in the cold, but here are a couple of videos. During the second (longer) video you can hear our conversations including our meeting Juliano and his daughter (or grand-daughter) from Naples, Italy. Like us, Old Faithful was going off as they drove up and they had to wait with us to see it. But after several tries, the large one doesn't want to load. Maybe when we get home... Or maybe it's too big. So here's a bison picture instead.
