Kids courses are weird. I have a really low overall average rating partly because for a long time I was playing golf with my kids, so I was looking for shorter/fun courses. Some short courses are fun and some just suck, but fun factor has always been hard to quantify.
I'm not from Alan Beaver's area so I have no knowledge of the course in question, but a course I find the reviews of entertaining is
Horizion Park in the Chicago 'burbs. Everybody says the same thing about it; great execution of what it is. What it is though is a kids/beginners course. So how do you rate it? To put a number on it is a struggle. To me, you have to rate it low; you can't give a 1,600' 9'er a three no matter how well it is executed. Since you can't give the designer credit for what they did with the rating, you just have to leave good info it in the review and hope somebody reads it.
Knowing that, when I went places with my kids I didn't look at the courses with ratings over 3. We were looking for short fun gems, and all the short fun gems have a rating hovering around 2.
If I had been in the area with my kids looking for someplace to throw and saw DiscGolfCraig's review, we would have thrown Red Bank. My rating of it probably would have been in the 1.5 range I gave Horizion Park. Like with Horizion Park, the rating has more to do with the weakness of the one-size-fits-all rating system where a course like Red Bank is rated on the same scale as Idlewild than it would with the execution of the design.
Those of us that have been on DGCR for a long time and write a lot a course review "get" that limitation. Alan Beaver probably is too busy to be on the Internet enough to hold that level of understanding of our thing here. Given that he's a PDGA HoF member and the rest of what we know about him, we should probably give this current example a pass and move on.
