We ate at the Old Faithful Lodge before seeing the Geyser go off. The food was good, but the inside of the place was very impressive.
Old Faithful took 90 minutes to go off! They said it use to go off every 60 minutes, but has been taking longer these days. It didn't seem to go off as high as I would have thought either. There were smaller Geysers going off and from a longer distance away from us we could see them really well. Perhaps one day they will be the "New" Old Faithful.
