As kids,Brad and I were always looking for something to do,walking around Portland,it was safe then,climbing the big cedar in the yard,whatever.Brad threw a rock at me once,I ducked and Cherie got hit in the head,as she was a few feet behind me.Rocks were never to left on their own,as they just layed there,calling out to be moved to another area,which may be more interesting.We being little guys,could hear them,so,we moved them in every direction,and fast as we could,at times.Cows,birds,squarrles,nothing was left to chance,we gave them an opportunity to help pack off rocks,they always retreated,none could carry them.Dogs seem to understand rocks,we never threw rocks at dogs,but if you bend over,to look at a rock,dogs,intuitively know nothing good is going to come of it,so they run off,being crowd pleasers,they don't want any trouble.Dad would later teach us about letitrights.It's an interesting rock,but,you just leave it right there,don't bother to pack it off,the rocks were happy at their present location.
