I played there right after the opening. To call the golf course Mackenzie is somewhat dubious; a similar claim is made at Pittsburg Delta View Golf Course and Mackenzie never set foot on the property.
Haggin Oaks is actually pretty good. There are some nice wide corridors that challenge golfers to find the right angle and some green contours that are a lot of fun. The bunkering, however, will never be mistaken for Mackenzie and the routing is not true to the original. As a municipal golf course, however, the place is well above average and there are many other places that suffer in comparison.
