Pros:
Quite fun with a chance at an ace on every hole. Much variety in type of putts. Especially good place to practice anhyzer putts and other shaped putts. Easy to navigate (because you only take a few steps to get to the next tee.
Cons:
Not quite finished. Some blackberry sprigs to scratch your legs.
Other Thoughts:
It looks intimidating because the brush is very thick. However, there is always a flight path to the target, and the paths you need to travel are getting stomped down. Bring anybody to play, they'll have fun.
Good use for the old baskets.
