Pumped the water out of my swimming pool for the last time yesterday. This is a Clark pool bought by my parents in 1967 and it has been in constant use for 50 years. Pretty good effort with 3 new liners in that time. The current liner has been in for 18 years and I figured it was getting to the end of its life. I did think of filling the hole in with grass clippings but nobody thought that was a good idea so now I am just going to put a deck over it
