Amen.
If the weather was anything resembling decent, gramma and mom both would run us right out the door, with orders to "go play". We didnt have to be told what to play, what to play with, or have anything electronic to do it. We made our own games up, ran, climbed, got scraped knees (gasp), all the things kids are supposed to do. Mom was eternally proud of my brother's bone deep tan, (I couldn't tan if you buttered me and put me the oven overnight), and the way both our hair would sun bleach to blonde every summer.
Now parents slather their kids in sunblock just to go from the house, to the car, to the store, and back, would have a heart attack if they spotted their kid climbing a tree, and a scraped knee is a reason for panic. They would rather plunk them in front of a tv than let them be kids and take a few risks, not to mention it is easier than having to actually "watch" them.
