Hi,
Thanks for all the suggestions! The pool is an inground and it is gunnite (I hope I got the spelling right). I actually have some pics of it and I will try to post. It's hard to see much with the "lattice" cover and you can't see the bottom because the water is so dirty.

We didn't see anything like freeze cracks as far as I can tell. Like you said (Al), we don't really have freezing weather here in Houston. We have had a few days during the past two winters where it dropped below freezing. Of course they shut down the entire city here. People freak out about the possibility of ice on the roads. I am sure those who live up North get quite a laugh over this.

We did get the bid on the house, as it is a good house that we really like. We have a 12 yr old boy who might be interested in fishing out some frogs with a little incentive.
