Pros:
The Energy Rotary course combines an interesting collection of small trees and bushes with moderate hole distances to make for a semi-challenging play fit for players of all skill levels. The mostly unrestricted high ceilings allow big arcing lines on most holes for more advanced players with sky hyzers and tomahawk shots being obvious first choices on many holes. The lack of really punishing rough means that beginners will be able to throw without too much concern for lost discs or thorny lies.
Nice views: If you live in Wyoming or Montana, you are probably quite used to the expansive views of the plains but for two travelers just passing through, the difference in scenery was really cool and the vastness of the surrounding area was beautiful. We played here right through sunset which is a spectacular bursting of colors due to the nearly 360 degree view available at the course.
Memorable: The course is memorable because you almost feel like you are playing through some kind of strange orchard or arboretum. There are tons of different types of interesting trees and shrubs all around and there are rows of trees rather than a natural scattering. This all makes for some unique images that have burned in my memory from this course.
Solitude: We played Rotary on the same sunny late summer day as Dalby and found this course completely empty of both golfers and any other park users with the exception of a few cars driving through. The solitude made for a really peaceful, quiet round with only the sound of the wind whipping through the trees.
Tees/Baskets: Nice big concrete teepads and solid baskets are another upgrade that Gillette has on the neighboring Dalby course.
Cons:
While comparatively, the Rotary course far, far exceeds the challenge available at the only other Gillette course, very experienced players aren't going to get all that much out of this course. Because of the nearly exclusively low-lying tree obstacles and bushes, anyone with a good amount of power can throw sky hyzers up and over obstacles. In this way, players will likely only have to control distance and manage wind direction. These big hyzers, even if poorly thrown, at the very worst will leave experienced players with easy par approaches because they negate most of the available course obstacles and leave the player with very short distances to the hole. Course variety is plagued in much the same way, with players too often being able to have their choice in route to the pin rather than being pushed to throw new shots.
Filler holes: There are several filler holes which are nearly entirely wide open and serve mostly as connectors to other sections of the course. Because the space is so large and many areas are nearly treeless, I can understand why these are necessary although filler holes are never an ideal course characteristic.
Maintenance: Nothing too bad here, but when we visited the grass was getting pretty high in some places meaning you had to search around a bit to find longer drives into the deep grass.
Other Thoughts:
On the whole, the Energy Rotary course makes for a nice way to break up a long trip and its location right off of the highway means you'll be back on the road in no time. It isn't a course that anyone needs to go out of the way to play but does have a lot more to offer than the nearby Dalby course which I would skip altogether.
