Pros:
Gorgeous course, with an excellent layout and great variety of holes. From technical doglegs and elevation changes. A lil bit of water, long open field bombs. They have it all.
You will use nearly every disc in your bag here.
It's a public park. The grass, brush, branches, and trees are all trimmed, pruned, cut and maitained by the city. The park facilities are also maintained fairly well.
Concrete teepads that are all fairly uniform in length and width.
Great baskets and multiple pin locations that are changed throughout the year just add to the variety.
There's a great base of regulars and league players who observe etiquette follow rules and are generally helpful to newer and less experienced players.
Difficult to lose a disc here, but definetely not impossible.
Cons:
Doesn't flow particularly well, with a decent bit of walking in between some holes and the next teepad.
Can get really crowded with non-Frolfers on nice days, Picnickers in fairways, bikers, walkers, joggers.
Can get really crowded with Frolfers on nice days as well.
Large population of homeless they are all fairly harmless just weird. Not to mention they've started combing the creek and surrounding areas for discs that they like to sell/trade for cash, beer or w**d. So don't lose a disc, chances are the homeless will get to it before someone who might actually call you would.
As a whole the leaguers and regulars are all very nice, but there's a select few that are elitist jerks i.e. I regularly play in a group of 3-4, however the leaguers commonly play in groups of 6-8, on the right day groups of 10+ are common. If you ask to play through or even play with in hopes of speeding up your round "Sorry Bro, this is a league game you're just going to have to wait" Is a fairly common answer. But like I said 95% of them are good dudes.
Other Thoughts:
Overall this is an excellent course and I'd rate it as one of the Top-5 courses in the Southwest Washington/Portland Metro Area.
It's my 2nd favorite behind Pier Park, If you consider yourself an intermediate or even advanced player this a great course for you.
Edit: As of 6/27/10 the baskets have been moved back to their original, more challenging locations.
