Thanks Fran.  We didn't have toys that used batteries or plugged into the wall socket. We would find a broken baby carriage or wagon and make a hot rod with used/straightened nails and whatever boards we could find instead of having 4-wheelers and dirt bikes.  We climbed trees instead of cutting them down. When it got hot, we opened the windows and doors instead of turning on an air conditioner. Kids communicated with their friends across the road by yelling instead of texting on throw-away cell phones.
