We had a really great time at Lark Valley Zip Lines. It was exciting, quite the rush to jump off a 20' tower and zip down a line several hundred feet over the woods and a pond. The guides were great. They explained everything and were very patient with everyone in our group, including 4 small children. My only concern was landing. You come in so fast on most of these lines you've got to be ready to hit the ground running as you come in or you're going to crash. I had a hard time and I'm athletic. All in all it was a great time and I appreciated the young men who were our guides.
