This tour was absolutely perfect for our little group, including two 70 year olds and one 18 month old. Not the scary, fast, bouncing trip the rest of my family opted for but over the course of our vacation, my group had so many factoids to share. JC is incredibly knowledgeable about everything, geology, botany, zoology, history, Indian lore, vortexes. His knowledge was so vast we wondered, after the fact, about his background.
