It's just a walk in the park

My main fun yesterday was going for a walk with Jack at Reid Park. We went all over the place, pausing to take some photos at the rose garden. There was an ice cream truck there and the atmosphere was festive. Kids were feeding the ducks in the pond and getting chewed out for playing in the waterfall. Others were being pushed ever higher in the swings.

I find it wonderful, that, even in this age of electronic everything, kids still enjoy swinging. Remember Robert Louis Stevenson's poem? 

The Swing

How do you like to go up in a swing,
Up in the air so blue?
Oh, I do think it the pleasantest thing
Ever a child can do!

Up in the air and over the wall,
Till I can see so wide,
River and trees and cattle and all
Over the countryside--

Till I look down on the garden green,
Down on the roof so brown--
Up in the air I go flying again,
Up in the air and down! 
     
--Robert Louis Stevenson

Here's something I was wondering: Why is it that, no matter how warm the day, no matter how warm the water, whenever you step under the shower, you always break out in goosebumps?
