around here they have in ground pools with wooden sides and vinyl
liners. a old friend had a pool business doing this kinda install.

way cheaper than steel reinforced concrete...

depending on the area a in ground can drive down the price of a home
for sale since they are a lot of work and few people want them.

in any case you need a fence for your and others safety, imaagine the
horror of coming home and finding someone dead in your pool.

that occured to a realtive of mine a neighbor went for a dip and
died...

they had the pool bulldozed and filled in then had to move, with the
neighbors kids still there it was so sad.
