Pros:
Only 18-holer inside the Saint Paul city limits.
Prodigy baskets in good shape.
Baskets stay up in winter (not true of all MN courses).
Free to play.
All concrete tees in good shape.
Other Thoughts:
This is the favorite course of one of my regular discing companions. It has a reputation for getting a bit crowded in the summer particularly on weekends. I played it on a weekday with 1" of snow on the ground and found it to be nearly a ghost town with the exception of a few dog walkers and one other player about 4 holes in ahead of me on the back nine who was carrying a shovel and cleaning off the tees. Thanks a million, Anonymous Dude.
The underlying property sits about halfway between an open park course and a woods course, with trees in play on every hole, but no overly pinched tunnels. The front nine plays on the south side of the access road, and the back on the north. UDisc offers a "Winter Layout", which is just the back nine, but all 18 holes are potentially playable year round. Interestingly, the concrete tees on the front nine are larger (approx. 8' x 12') rectangles, while the back nine tees are keystones significantly diminished in both dimensions. Apparently the aforementioned Anonymous Dude skipped the front nine, but traction was reasonable even with 1" of snow, and, as a bonus, someone left a self-service shovel hanging from a branch next to the 5th tee.
You don't need to be a bomber to play Highland Park, but it's no pitch and putt ace runner either. My favorite two holes were #3, a poker straight downhill tunnel losing about 25 feet of elevation, and it's opposite, #5, which is both shorter and wider, but marches you back up the same slope, requiring a somewhat technical steeply inclined drive. The staircase on #5 is much appreciated.
I could see myself playing a lot here if it were a little closer to home. Being the only 18-holer in Saint Paul, it claims the "best of" in that category by default, but I think that it is really just about everything that you would hope an urban park course would be.
