One of the grooviest things my dad did was to hang a swing from a really high tree branch in our back yard. He would give us the most powerful pushes which enabled us to touch branches with our feet. My sister and her husband have done the same thing. It's the simple things that bring such joy. The expressions on my friends' son's faces say it all. Hang a swing in your yard and create joy and great memories for your kids... and joy to the fishes in the deep blue sea! Weeeeeeeeeeee!
