When my family heard "walking tour", there were moans and groans... until 2 hours later when they returned. The moans and groans had become exclamations of delight: "So interesting! Who knew!" "The very best way to see Boulder!" "Lori was so full of fun, and facts, and interesting information - a gem." "I can't believe that was 2 hours, felt like 2 minutes."
You absolutely, positively must do this tour. You will love it!! Lori is the perfect tour guide, with a warm and engaging, insightful and informative vibe. She cares about what she does and makes sure that everyone is participating in a way that works for them.
