I went bouldering with my two boys, age 10 and 12, and was guided by our fabulous leader, Fred, his son, and his fabulous dog, Nessie, who was a better boulderer than all of us! It was a great day and Fred was a great instructor - patient, energetic, safe, and knowledgeable. My boys are new climbers and I have recently started climbing, again, after a long hiatus. Fred found stuff for all of us to do and helped with great feedback and beta. He also climbed everything we did in jeans and sneakers, so I am fairly certain he would be an equally impressive guide for hard bouldering, too :)
