Pros:
The Griggs "Riverside" course in Columbus, OH was clearly installed over the plain along the Scioto river where there once was a campground facility (you encounter the old asphalt drives as you go). It does utilize the available rolling terrain on holes 1-3, and the uphill treeline on 4, 5, 10 & 11, as well as the trees guarding you from putting any in the river on 8 & 18. It is interesting to see that none of the holes really put you at any real risk of going in the river, which might actually be a plus, because retrieval there would be very risky, if not impossible.
Sporting a variety of hole distances (220 to 454 feet in the B positions), the course seems geared to benefit folks with Intermediate distance and above, because it's open enough to set longer arms up for deuce opportunities, while recreational arms (max 'D' 250-280') will often be playing for a three. The course seems to be very popular with (casual playing) young men who can bring their girlfriends out and impress them with long-ish drives (especially if they can drag along a noob buddy to put their skills in perspective. But it also plays well as a tourney course because of the Columbus Flyers' own Paul Jay's creative use of OB, island greens, etc. If you play with strict OB rules for the drive and walkways, there are plenty of opportunities to stray, and add strokes.
Having a nice park kiosk map sign at the first hole, benches where appropriate, one set of level, flush, well-proportioned concrete tee pads (I love the grooved traction strips at the front and back ends!) and decent DGA baskets in either of two pin positions, the infrastructure here at Griggs is sound. There are a lot of baskets out in the open, but the ones set into the woodline create a fun but fair challenge.
Cons:
The park entrance could use a sign for newcomers, and they should be encouraged to bring a course map, because of the confusing, crossing flow between 5 to 6 and 16 to 17, plus the somewhat blind pin positions on 4, 5 & 18. When you stand on the 5th tee, the basket you CAN see is for hole 16, yours is just short of there, in the woods, right. And when you stand on the 16th tee looking at a line of three baskets spaced in about 100' increments, your target is the first one (though if it's safe to do so, I suppose bigger arms probably safari on out there!).
Speaking of signage, the course could use an update here. Now that there are multiple pin positions, it would be great to have these upgraded to ones with schematic maps and both (all?) distances included. And though the new basket position on hole ten is excellently placed uphill in the woods, it ain't either of 249' or 265': it's a much longer hole.
Personally, I'm not a huge fan of the fact that the course had to be shoehorned into a very long and narrow strip of land, eliminating the possibility of getting two loops in. The ideal in this situation might have been to figure a way to arrange parking in the middle of the strip, rather than at the south end only.
Finally, there are a few holes (4, 8, 17, 18, maybe others) where you'll need to wait to make sure non-players walking, strolling, and sometimes pausing on the path are clear before you throw. And many of those folks seem a little clueless that you might hit them.
Other Thoughts:
This is obviously an established, heavily played course, well enjoyed by the Columbus disc golf scene, and may be the strongest option on the west side of town.
