Thanks for your fast response on my mermaid question. I am also concerned about the problem of water in your back yard. I live on a rectangular shaped tidal basin of about 13 acres. It is very pretty- like a big reflecting pond. My house faces south,and the basin is attached on the far side to a canal that drains to the east (right to left looking from the back door). Street access is from the north side,and guests enter from that side too. We enter through the garage,but use the back door probably the most going out to the garden and for pets. What do you think?
