" Greg took my family (my husband, myself, and our two adult "children," ages 24 and 22) throughout the Tetons the first day and the lower loop of Yosemite the second day. We had to power vacation since we had only a few days to see the most we could. Greg didn't disappoint. We loved being able to kick back and enjoy the scenery with a knowledgable, well informed guide. I would recommend BrushBuck Guide Services to anyone going to Wyoming. "
