Pros:
First and foremost the biggest pro is the challenges that this course present. Many shots are tunneled in between and underneath trees. This course was clean and well kept in all areas (open and wooded). It was fairly easy to navigate and the maps on the signs at each tee box helped immensely with that. There were nice restrooms available here as well. Also, there was a great mix of short to long holes (200' to 475') at Thomas Park. And lastly, it was great to play in the wooded area most of the day, then pop out of the woods here and there (1, 4, 11, 15, 18) to play some more open holes. Great design.
Cons:
If you do not pay attention to the signs at each tee, you will lose your way from time to time, but other then that, fairly easy to navigate.
Some of the holes started to feel the same as previous ones, but not too often.
Also, there were a couple of holes (and #14 in particular) where there was no path through at all.
Very tight and challenging, so course is easily frustrating for beginners.
Other Thoughts:
This course is a must play for any passing through. It is not far from I-70 and very easy to find. I can honestly say that this is one of the very most challenging courses I have yet to play!
