Who grew up playing on metal playground equipment? Did you enjoy it?

When I was young all the playground equipment was made of metal frames - jungle gyms, swing set frames with chains we used to swing as high as we could, and sliding boards we sometimes slid down on stuff that made it more slippery so we could go faster :-)
The metal got very hot in the summer and very cold in the winter. We learned to test the metal surfaces first and slide down on coats in the winter months or old rugs/towels in the summer and never to stick you tongue onto a very cold surface :-)
When my kids were young sometime changed the metal playground to wooden playgrounds for a time until the concerns about splinters drove the designs to plastic, ergonomic play equipment :-)
Do you have food memories of playing on metal playgrounds or the later versions? Are you encouraging your children or grandchildren learn to play on playgrounds?
