How come some wooden coasters (which AFAIK are harder to maintain
than steel coasters) have been 0perating for over 100 years but this
apparently has reached the end of its service life after only 25 years?
I remember my family did that once. It ended up with more fighting than fun, and my parents eventually got sick of it and ended up picking everything themselves. It's pretty hard to agree on anything unless you're an only child.
