Pawpaw and Mawmaw and me

I don't know what year this is or how old I am. I have a very vauge memeory of this. We were on a dam somewhere in Arkansas.
I was born in 1957 and I was the only grandchild until 1961 when my cousin was born. I was probably spoiled rotten!
Helen and Elec were my maternal grandparents. I loved them so much and I miss them!
