After dinner with Matt and Em at Slippery Otter, and sleeping in street at W. Yellowstone we 4 took off early. Cloudy and 65. Hit Old Faithful and then 3.5 miles around the trails, so many awesome geysers - Riverside #1 and Grotto #2 although we didn’t see the Grand Geyser erupt. Then we hit the quick tour of the the Black Sand Basin. Short hike, but must see. Skipped Biscuit Basin to get to Grand Prasmatic.
