Pros:
-A decent course in an area without lots of disc golf options
-One of two 18 hole courses in the same place, and it's less crowded (by other park inhabitants) than K2, the west course
-No fees, good parking, and the park is well-maintained
-Baskets, though aged, are good (I prefer Mach to Chainstar)
-Multiple pin locations -- what really got me hooked on this course is when I played it on the "long" layout; it makes you feel amazing when you get birdies, and makes you work to save par after even slight miscues - my 2.5 rating is for the harder layout; 2.0 or even 1.5 if in the short pins
-Few places to lose discs! (though I've managed...)
-Some highlights:
1) good forehand shot needed (RHFH) to get past trees for a shot at birdie
3) tricky shot along the OB street, requiring precision to get over the short fence but stay under some trees; one location is in the "island" between the two lanes of the street
8) distance required, and there are some early obstacles to avoid; one location is a nice basket up on a mound, one is in a nice "tree-enclosed" green, and even the short location presents a challenge
11) fairly long with a partially obstructed tee; all pins require adequate power and line-shaping to get a two; wind frequently factors in disc selection
12) now throwing a fairly long shot again, with opposite wind; slightly uphill, and the long basket is nestled up against a wall; the short basket requires a good line to get into a somewhat sheltered green
15) long drive either over the OB park road or layup before; two of the three hole locations are particularly challenging/commendable: one nestled in among some trees on the far side of the street, and one maybe 100' past the street with a pesky bush in the "green"
18) tough in all pin locations; I love the long, where it's a legit par 4 requiring a good layup and a challenging approach to have birdie possibilities
Cons:
-One of those courses where it feels holes are kinda placed wherever they fit; a couple of these don't really feel like golf shots (4, 9, 10, 13, 17 all come to mind - but even these are fun to play)
-At least one hole (5, in middle/long positions) is pretty much impossible to birdie because it requires such a crazy dogleg to the right; there are a couple others where you have no idea what shot the hole is "designed" for. This is likely because trees have grown since the course was designed.
-Two holes throw over a park street, and it's common to have people picknicking, kite-flying, or playing catch/softball in "fairways," on average once per 18 holes; this is a byproduct of disc golf not being a big sport in this area (the problem is easy enough to solve with communication or occasional hole-skipping)
-Navigation isn't stellar, partly because of the pin location issue and partly because of a parking lot and street between some baskets and the next tee. The first time I played, I skipped at least one hole and threw to 2 or 3 wrong baskets before realizing my mistake.
Other Thoughts:
I believe this is the oldest course in the area. It may have been better when new in the 90s, but both the park and the game have changed since then. Changes to the park have altered some holes and forced course managers to move a hole or two. Tree growth has removed some lines that were probably present 20 years ago. Longer discs (and forehand shots) have removed some of the challenges that were originally designed into the course.
K1 has grown on me! This is a course that's quick to play, and there aren't many around, so I play it often. It doesn't feel like a full day of golf after just one round (particularly when baskets are short), so I sometimes play twice or move over to K2 (west) for a second round.
