The lot across from our house is an empty one and has a great rock pile left over from building another house. The boys love to climb on it which is good and bad. Easton is old enough now to do great on his own with limited supervision. Kesler on the other hand needs A LOT of help and still tried to keep up with Easton. Soren usually gets the job of supervising. This time we got smart and put helmets on everyone.
