Last year I took Mr. K (then 3-years-old) to the Freedom Festival. Kal'el saw this bungee jumping "ride" and asked to go on it. It totally freaked me out and I didn't think they would let him on because he's just a baby, but they said he was tall enough. The line was 45 minutes long. I was sure he would chicken out after he saw everyone being flung 40 feet in the air. We got in and I insisted and standing next to him (seeing my baby flung way out of my reach kinda freaks me out.)
I thought Kal'el would panic, but he was so excited and had the greatest time. Look at the expression on his face.
