Pros:
Longer, steeper and more challenging than expected.
-4 tee pads on 'Front 10' really let you work your game.
-'Back 10' is a more of a 'Mountain DG Approach Course'.
-Flexible. You could play 5 minutes or 90 minutes.
-A great way to fill time if your group gathers slowly.
-Allows work on shots required by the main course.
Cons:
These are pretty minor nits to pick:
-Some tee pads hard to find.
-Some criss-crossing around the base area.
-A little weed-whacking could help.
Other Thoughts:
Bluebird is really two different 10 hole layouts. The 'Front' has 4 tee pads per basket. Each 'pad' is a color coded wood block and a few were a bit overgrown but find-able. The length and aspect of the 4 pads provide a pretty tough putt for Rec, Int., Adv., and Pro players respectively. However, since I had time, I enjoyed playing all four pads, roughly like shooting a 'Lay-up', a 'Free Throw', a 'Three Pointer' and a 'Four Pointer' on each hole. Several shots were worthy of more re-throws than I care to remember.
The Front winds around the base area and I suppose on a crowded day there might be some courtesy waiting...but hey, it's putting. No helmets required.
The 'Back 10' is an entirely different deal. There is one pad per hole and unless your name is Ricky or Paul, this is an Approach Shot Course and a really good one. What I loved was being forced to work on shots that the main course can punish you on...rollaways...tree doinks...footing issues....elevation.
Since I threw multiples on the steep Back 10 as well as over 100 putts, I actually got in a pretty good 90 minute work out. But this course literally has something for everyone, and I can't say that about several other warm-up courses I've played. Highly recommended.
