First time ATVers - it was awesome! Scary, yet thrilling and exciting. Don and Tammy took us on a very diverse ride with lots of ups and downs (amazing how vertical you can be in an ATV), bumps, corners, and speed - tough rugged terrain. Don and Tammy also provided breaks to share information about certain sites, dinosaur tracks, and give one a chance to catch their breath! Would highly recommend the Grand Company Tours and them as guides!
