Thanks Nick, it was a lot of work, it took all summer and it was a real dry year but it was all worth the effort. Just me and my two boys, young men actually 21 and 22 years old at the time and it cost between 6 and 7 hundred dollars to make but that was
scrounging and mixing everything ourselves. We even got the sand for free for the concrete. You can do the same thing with a pond liner too and I have seen used rubber roofing pretty cheap on Craig's list so if you got the land and the gusto go for it.
Thanks for watching and God bless.
