My son and I did an introductory climbing day a couple of years ago with Sylvan Rocks. That day made my son fall in love with climbing. Last week, we returned for a three-day climbing session, and it was even better than the first. Our guide Shankar gave us three amazing days that culminated in my son's ascent of Spires 2 and 3 of the Cathedral Spires in Custer State Park. He was patient, good-humored, and laser-focused on safety while dealing both with my beginner's mistakes, and with my son's need for technical training. While he pushed me to stretch my limits, there was never any point at which I felt it was inappropriate. And, we got to the top of the "Aquarium." On top of all that, Shankar's just a really cool guy. I feel that we got more than our money's worth out of this experience, and we will be back to climb again with Sylvan Rocks.
