My backyard swingset.

It is 12 and a half feet tall. It weight about 380 pounds and is set in 960 pounds of quickcrete. I love swinging on it as high as I can.

It looks like the type I had as a kid at school. I loved trying to do a full 160° but never came close. It was fun to jump from and see who could go furthest an "stick the landing".
The strap seats are the best, those flat plank ones aren't as fun.
It's all about banned on playgrounds now. It was all asphalt to land on then and that was a bit rough.
