Today the girls decided that Issac was old enough to be riding without training wheels.  They took his trainers off his bike, grabbed their own bikes, helmets, and first aid kit, and wheedled him into joining them for some bike riding lessons.  By the time they were done he was able to travel several feet on his own and I realized that he needed a bigger bike.  (also, posted a new painting at–One Sad Bunny.)
