Hey everyone, new here to the site but love the whole community so far. Myself (19) and a buddy (looking for two more to join...) are planning a trip out to Yellowstone from the Boston area. We feel like we are prepared for the journey, we have quick stops planned in Niagara Falls, a little longer in Chicago, overnight at Mt. Rushmore and then finally ending at Yellowstone. We are just curious if anyone has done this route from the East Coast (Boston Area)? As this is our first big trip we aren't sure of the timing for the trip and stops. We are planning a 9-10 day trip there and back, too short or too long? I would love some insight about our trip and any suggestions for us. Anything is appreciated. Thanks. Evan.
