rating playground equipment

The summer weather has hit us full force, so the little ones and I have stepped, blinking out of doors, which is a nice change. I’ve decided to find every playground within a ten mile radius of my door this summer. So far, every one of them has had its ups and downs (teeter totter pun). Overall, as a sun-hater, I prefer the shaded ones. But it’s not about me is it. I've devised a little rating of each piece of playground equipment. I’m sure I’ve omitted some, so please send me lists of whatever I've missed, or your own ratings.

The Slide
Takes a certain amount of bravery, and effort, each time to get up to the top, but the final two second thrill of hurling yourself down a slick surface is entirely worth it. The twisty slide gets extra points for bravery, since your final destination is not always visible. The hot reflective metal slides of my youth are a dying breed, being squeezed out of playgrounds by plastics, so the dangers of scalding bare legs on a scorching summer day is greatly reduced.

Swings
The most sedentary animal of the playground. Requires the rider to simply sit stationary. Can be pushed by a ground dweller, or with a minimal amount of effort move their legs back and forth below the knee to start the pendulum swing. An all purpose piece of equipment. The highest highs can emit big thrills, while the leisurely melodic swinging can induce contemplation and introspection. Bonus points for tire swings, where the option of sharing a ride is possible.

Springy Riders (do they have an actual name?)
Solid hunks of metal, often in the shape of odd animals or vehicles, mounted atop a large spring, which is stuck into the ground. Their appeal ends at their bright colors and shapes. The rider must throw themselves into rocking the beast, while it springs back to its original position after each movement. Generally not even a good spot to sit and relax since it usually requires the sitter to straddle it, feet in stirrups, body leaning forward, gripping on the handlebars. No child lasts more than 1 minute on these, guaranteed.

Sand
Feels wonderful on bare feet or hands when dry, and is malleable and moldable when wet. Invokes unbounded creativity. Can be a delicacy for the young and a dirty weapon for all, Often of questionable cleanliness.

The Teeter Totter aka Seesaw
