Pros:
I recommend going back here if you were bored with the old Acorn, it is very different and enjoyable. I think there are only 2 holes that were untouched, and a couple others slightly modified, the rest feels completely new even in the same space.
The excellent visual on the tee shot for #18 is the same, as is #1.
#2 is in a completely new space, and a decent, short, narrow lines challenge that is often swamped with water.
#7 is grand, an improvement on the old #9 (which was very good) in almost the same space. Includes decent length, two water hazards, a tight window at the start, and probably the need for limiting distance/targeting an area on the first throw to set up a bomb for throw two.
#15-17 completely revamped the space that was 16-17 before. I can't believe they improved these so much in the same space:
#15 is a challenge to get out of a ravine with very small windows to do so.
#16 is short, but blind with another tiny window.
And #17 just gives a great new view to the basket at the end, between two bushes. Not much challenge, though.
Cons:
The biggest con has not changed. This is one of the busiest courses in Minneapolis, and all sorts of idiots like to trash the place. What is wrong with some of these people? Just stop trashing parks!!
Also, #5,6,8-14 are a little simple. But it is a free park and hey, go for birdies, feel good.
Other Thoughts:
I have to disagree with one review, last time here I shot a -6 with 8 birdies. But, that probably agrees with other reviewers that half this course is pretty simple pitch-n-putt, because I'm not that good!
