There is no Canyon Retreat Neighbors newsletter as such. If folks make frequent use of this web page it could serve that function.
Mountain Park Ranch features the latest issue of the Association newsletter on the MPR web page. Get there by clicking on "Back to Canyon Retreat Neighbors Home Page" at the end of this article, then on "Mountain Park Ranch" under "Community Hotlinks."
There is also an MPR site on the Neighborhood Link network. Click on "Neighborhood Links" in the left margin here, enter zipcode 85048, and choose Mountain Park Ranch from the list of neighborhoods.
