Hands down this was absolutely perfect for me! Solo and staying in Big Sky I took a chance and booked this last minute Yellowstone loop tour and it was perfect in every way! Joel was great! He truly knows the ends and outs of ALL things Yellowstone. His knowledge is actually quite impressive. Snacks, yummy sandwich, plenty of snacks and lots of water, and potty breaks. I would highly recommend to anyone looking to enjoy the park without the aggravation. With gratitude, Tracy
