The backroads atv tour was great! Keresa and Trey had me laughing the whole time, they are like Batman and Robin with how well they complimented each other. If you are lucky enough to have them be your guides, you are in for a hell of a time! The new atvs were great too, they are not limited to 15mph (like other companies) so these will get going quick!
One recommendation - if you go on a dry and sunny day (like we did) try and take a thicker neck gaiter to block the dust. They provide some at check in but they are a bit on the thin side but work well for the most part.
Overall I would still highly recommend when considering all aspects of the tour (drive, guide knowledge, stops along the way, jokes, and knowledge).
