Re: landscape ideas?
The first thing I'd want to do is fence and secure that area.
That is a good sized area and I would landscape it to be suitable for the type of use that suits you. If it's a "kids only" area, then look into jungle gym structure, sand pits, and other safe play areas. If this is more of an adults area with kid friendly things, then I'd do a nice patio or deck with a shade/roof structure for the adult portion and then the play set/structure for the kids off to the side in clear view of the patio.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
