I live and play in PA. There are many good courses in PA that I haven't played yet, but of the PA courses that I've played Nockamixon is the best.
Next time you go to your local course, pay attention to the "bad" baskets -- the "fillers". Nockamixon may only have one of these -- #4, and even it's a fun basket to throw. So many of the courses that I've played Nockamixon's "worst" basket would be their best basket. Would I rather play Idlewild (KY) than Nocky -- yes, but that's because the high-end stuff out-do Nocky's, but not by much. Although Idlewild's #4 is a worse basket than Nockamixon's #4, and Idlewild has another "filler" in #13 (right? -- that's the crappy little tunnel uphill thing that's been moved out of the woods by the tall grass but still is just a basket that you play and wonder "why is THAT here among all these spectacular baskets . . ?")
I've only played the peak course at Blue Mountain and that's just work. The base course is supposed to be "all that" but I haven't had the pleasure yet. If I'm heading north from Philly it's tough to pass up a round at Nockamixon, and if there's time a Nockamixon/Jordan day is borderline nirvana.
With limited time for commuting to a course I spend most of my disc golf hours at the best course within a half-hour of my SE PA house which is Iron Hill, but is Iron Hill the "best" place to play in PA similar to Idlewild (KY) being Ohio's best place to play . .. . ?? Probably not.
Is there anyway if I were from Ohio and had to drive to a course in PA to play would I bother to drive past all the great courses out in western PA to get to Nockamixon? Not a chance -- it's too damned far and the quality of the western PA courses just wouldn't make driving all the way east worth it -- Deer Lakes, Moraine, etc., more than hold their own against our eastern PA courses. I can't wait to get back out there. Last time I played Deer Lakes there were dirt pads .. . .
Is Nockamixon a better place to play than any other place in PA . . . yes. How's that for a short answer gone long?
