Yes, I've been to 'Mason Park' (when our son's were young they used to hold Scouting events there). As for the 'Mariners Church' I can only recall being on their campus once when I went with my wife to pick-up some religious books, from their Bookstore, that she needed and they were able to get them faster than any other store could (this was before Amazon.com).
We don't get down on that end town much any more as we live up in Northwood, almost to the foothills.
