Pros:
What they call an 18 hole course, crammed into the smallest plot of land ever, in Seattle. But let's be real...this is a 9 hole course with two sets of tees and a little variation.
Concrete tee pads, which were mostly good enough. There are a few sketchy pads that hinder runups, and several that may require standstill type drives.
Old school Mach 2 baskets, but they all caught well enough and were in surprisingly good shape, considering the course.
The course is kind of set against the side of a small hill, so you get a bit of elevation change on many of the holes, which is nice.
The course is mostly covered with mature trees, and many of the holes require specific lines to get to the basket. The design of each hole as a standalone entity is pretty good.
There were signs for most of the holes. They are the old school basic signs, but once you find them, do enough to let you know what's going on with the hole.
Cons:
Oh, where to begin.
Mineral Springs sits easily in my top 3 "holy @#$! this course is packed in a small space" courses. This place is like a game of Tetris...every damn square inch of space is used for frolf. In many cases, the same square inches are used for several holes, which of course leads to major safety concerns. Being the only course in the immediate area, you get all types here...soooo many chuckers (which is great...they need to frolf, too), dirty bums (more on this in a second), "old school" frolfers, and a few more serious players. i would wager that somebody gets hit with a disc (or 22) on a daily basis, as it's nearly impossible to know if there's somebody in your path. Easily the most dangerous course I've ever played...and it's not really that close.
Navigation is kind of a nightmare. As stated before, there is not a lot of rhyme or reason to the layout. Sure, some of it flows naturally, but there are a ton of holes that you'd simply be guessing at if you don't have a printed map or local to guide you.
Do you like dirty bums?? Well if so, this is the place for you! As a Midwesterner, I'm not used to rampant homelessness, so maybe I'm a bit jaded on this one...but having a tent city just off one of the fairways is disconcerting. Not to mention the faux-WalMart greeter that hangs out by Hole 1 and begs for spare change after regaling you with stories of his disc golf prowess, of course.
Soooo close to the roads. When you have to put up 30' high nets so discs don't go into the busy roads adjacent to the course, you're probably too close to the road. The worst part is, they couldn't even get this right...hole 5 has a damn gap in the net right at the point where newb hyzers are going to newb hyzer into the road. Deep in the chasms of my imagination, I imagine a shoeless dirty bum chasing his 1994 DX Roc into the road, dreadlocks flapping in the breeze and Seattle rain, and becoming a dirty bum pancake. I can't decide if this is funny or sad...I'll leave that up to the reader.
Other Thoughts:
So what we end up with at Mineral Springs is a bunch of relatively fun shots in the worst configuration and location you could possibly imagine for an urban setting. This would be a fun spot to play if it was always empty...but from what I was told, it's almost always packed. No options is a terrible thing in the pursuit of love, and the pursuit of frolfs.
Am I glad I played it? Yes, but only because I'm a sadist and love craptastic courses. Would I go back if I'm in the area? ONLY if I were homeless and ended up living in the tent city off hole 7.
