Pros:
Mt Vernon has a great course with lots of potential.
It currently has nine holes but has red and blue tees so it can be played as a 18. There is not much elevation variety but plenty of right and left variety. If you mix in the blues you will also get plenty of distance.
The park is groomed and mowed weekly no fear of ticks and snakes here.
There is a local club that host plenty of tournaments and a league.
The snow cone stand has the best snow cones in the world! Yes the world! When you come be sure to try one.
Cons:
No concrete tee pads yet. I hear they are planning on some in the future.
Other Thoughts:
This is a heavily used park be cautious of people walking, biking that sort of thing.
