Gpraceman...I wonder if we are neighbors!
The homes by Rocky Canyon High in the Wildcat subdivisions are considered Littleton and not Highlands Ranch, I believe. We almost bought a house in there and found out that there is no access to the rec centers. However, you do have the subdivision pool instead!
There are some great homes across from Rock Canyon which sounds like it may be what you are looking for, adlmast. I am not sure, but those homes may start at $600,000 and up. I haven't searched the web sites lately. RE Colorado and Colorado Home Finder are two great websites for searching.
