“This team was so focused, polite and hardworking and still managed to make it fun. It’s very hard to do this, but they made it look easy. I’m only sorry there aren’t dozens of similar programs throughout the state. Thank you so much.” –Gregory Rudd, Skyline to the Sea and The Trail Less Traveled 2016 participant

“This was a blast and with a great group of people. Most fun was the stories and the laughter. I learned a ton. More was covered than I could have ever imagined was out there. I never dreamed there was so much to know and I’m very impressed with Alex and Jeremy’s knowledge.” – Jennifer Hardwick, Skyline to the Sea 2016 participant
