More from the park

 Telephone booths are very unusual these day. Everyone has a cell phone so the public phones have rapidly disappeared.

 The slot at the right top allows you to deposit coins. The large horizontal slot in the middle is for a pre-paid card. And the red button at bottom connects directly to emergency services without requiring any money.

 I found some exercise equipment. This is for moving your hips back and forth while holding the rails. The blue sign on the post shows how to use this.

 Here are some of the other pieces of equipment. Then nearer one is for stair climbing and the far one is used by putting your legs on this side and then hanging over backwards on the other.

 This is an example of how to use that last ladder-like thing.

This one was interesting. You are supposed to walk through it. The floor has various built-in patterns that stimulate the bottoms of your feet. I could feel them even through the thick soles of my walking shoes.
