Pros:
Well maintained, interesting pin placements, length.
Other Thoughts:
I was surprised by how nice this course is; even Baltimore's least known course is plenty long, well maintained, and challenging in a variety of ways. Other than a real right-turning hole, this course packs a lot of challenge into a fairly small space, and is great looking too. Also, Pine Grove has nine baskets but really does play like 18, with the second nine playing from completely different tees. But while I found all nine baskets no problem, I did not find four of the nine tees on the back, so you may wish to have a local guide or at least the benefit of local insight before you play this course.
This course also featured some difficult pin placements, with several baskets sitting on the side of steep hills or right behind some big trees. Without a good putting game, makeable pars can turn into doubles with a couple of barely missed downhill putts. But playing around the outer edges of a set of baseball and soccer fields, this course made good use of space, putting a legitimate 18 holes on space for only nine and making good use of the available creek, hills, and trees. Finally, the course doesn't appear to get much use at all, making it a good place for practice or a quiet round. If only I could've found all 18 tees...Oh well, overall, this course just boosted my opinion of the Baltimore area as one of the top places in the whole country for disc golf.
Favorite Hole - #3 - Down and across a couple of small hills to a basket well back in the woods.
