Pros:
Fantastic tee areas: Long, wide, level concrete pads, surrounded by a rim of mulch. Signs showing the distances/shape of the various pin positions, and also indicating which position the basket currently is in. Benches, and posts with plenty of baghooks.
Multiple pin-positions per hole. Several holes with multiple tees. Between the map and many directional signs, the course was quite easy to follow.
Very nicely groomed. Many mulched walking paths, lined with cut logs, and many mulched greens, too. Uniform, ~7ft. high triangles-of-logs used as obstacles on some holes. Not a bit of trash
Cons:
Longish walks and/or re-tracing of steps between some baskets to tees.
Other Thoughts:
The course is set, primarily in the wooded area, and bits of neighbouring open space, in a portion of a very large, public park. Disc-eating shule is minimal/non-existent on the wooded holes, and the out-of-bounds tall grass found on the open holes is typically a decent distance off the fairways.
With three wildly-differing length (average of ~225' short, ~350' mid, ~420' long) pin positions per hole, you won't know what you'll encounter when you visit Tyler, but it's all good - quite good. The day I played the course, 1/3rd of the baskets were in the A-pins, ~1/2 in the B, and only a few in the C.
In addition in the variety of distances you'll likely face when playing the course, you'll also have variety regarding ...
- Elevation - Flat? Of course. Subtle up/down? Yeah. Steeply down/up early/late? Sure. Up-n-over rise/across valley? Yup. Continuous/variable? Got it.
- Shape - At times you might feel as if you're throwing a lot of right-turners, and other times, left-turners, but as you review your round on the whole, it appears to balance out Turns vary from subtle to sharp, and for some the C-pins, the turn for your approach will often mirror that of your drive.
- Tightness - from wide open to challenging-but-fair, nothing uber-tight. On most holes, errant throws will still offer a chance to scramble to save par.
Favourite hole - most of them? 23B is the one I remember most. Straight up the hill on a narrow path, thick trees along the left, thinner line of trees road on right. Assuming you make it to the top successfully, another straight down-the path shot to the left is needed, with just a touch of fade, as the basket sits on a steep, wooded slope - I was thrilled with my '4'.
I have yet to play a poor course in a PA State Park, and many of them fall into my top 10% of the 260 courses I've played. With Tyler, Nockamixon, and other good courses to the East, Deer Lakes, Moraine, and other good courses to the West, and Quakers, Whispering Falls and below-the-radar Coyote Hill in the Central, think Pennsylvania for your next extended disc golf vacation!
