Pros:
As an admirer of any course with multiple tees and basket positions, I found this nine holer to have an intriguing amount of variety in a small package. Even though six of the long tees are simply further back, the variety of lines, and new plantings of pines on three of the holes mean that you'll need a little more in your arsenal than just 'more D'. The feature holes (3, with its steep gap putter drop shot, 4, which demands a precise, blind left to right line, and 8, which is an astonishing, blind, steep, gap-defying uphill to get out where you can see the basket!) show off the fact that there's plenty here to challenge the recreational to intermediate disc golfer, and enough of a 'difference' to amuse those with higher skills.
With 17 (only one pad on hole 3) fantastic, level, grippy, flypad tees and a set of nine beautiful DGA baskets (which include a small pad to protect your base line plastic from scuffs on the sleeve/lock assembly at the base of the pin), and clear (if very basic) tee signs at the long tees which list distances to the A and B positions from either tee, the park has evolved well in the year plus it took for me to come back for a second look.
Hole distances range from 153 to 375 feet, and the longest hole is a tight, wooded lane I'd be impressed to see deuced. There is more parking here than can possibly be used by the disc golfers who might play the course, as it is primarily there for the four well-kept ball fields just a terrace below to the west. The drop from the upper terrace to the lower is well-incorporated into the course as a throw (3 down, and 8 long up), or as a tricky green (2 and 9). There is talk if (and room for) more holes to be incorporated on the woods side of the park, along the creek, which could weather into quite a nice course, if it were to happen.
Cons:
There is a little bit of a challenge in the course flow and lack of 'next tee' signage, so I've added a schematic map here for first timers coming from DGCR (looking forward to the Columbus folks doing up a more formal one). If it's wet, you will want to walk left from the third tee to the concrete (and handrailed) stairs. After 3, walk forward to the second tee sign for hole 4. Be careful on the two holes in the woods, because they run parallel, and trees notoriously kick discs in unexpected directions! After 5, walk forward past the huge log, and trek the path left to the short 6th tee.
After 6, there is a steep path to get out to the open, but if it's slippery, folks might be tempted to backtrack to the gap on 4 (which could be very dangerous if folks are throwing there!). Then walk past 4 to the 7th tee. There is a more gently sloping, if circuitous, path to the left of the long 8th tee to get back up topside, and folks throwing long 8 should probably holler up to the top of the hill to make sure no one is in the flight path there.
Other Thoughts:
In all, the Whitehall course is pretty, well-maintained, and a different kind of challenge for the beginning to intermediate level player. There aren't any real grip it and rip it opportunities here, but there are plenty of those on the other courses in town. Finally, not being a native of Columbus, I can't speak to the notion that this may be an 'interesting' part of town, but I've been here twice without concern. My first trip in, the park was hosting a fairly sizeable softball tournament, and the teams and fans had camped out pretty much all over the course, so we weren't able to try all the holes.
