What an amazing adventure! My family has always been the do-it-yourself National Park type, but when the north entrance was closed because of floods, tours were the only option. This trip changed my perspective on tours. Nolan showed us so many amazing things and we didn't have to stumble our way through it. From wolves, bison in rut, the Ledge Geyser in its steam phase, and Mammoth Springs to ourself first thing in the morning, he exceeded our expectation by miles. We would highly recommend to them to anyone headed to Yellowstone.
