Pros:
-Deerfield has a lot of nice elevation changes. For example hole 1 is pretty steep uphill, on 2 the basket is in a ditch (but has a flag so you know where it is), 5 is a 515' downhill shot
-very easy to navigate. there are signs that point you toward the next tee
-probably the best variety of shots of any course I have played (which I have to admit isn't a lot). There are long(5), short(16), hyzer (9), anhyzer(17), uphill(1), downhill(5), shots along(13) and over(14) a pond, tight(8) and open(5) fairways.
-very challenging. Though I'm not that good, I consider it a good day if I score better than +10.
-nice cement tee pads on the pro and am tees.
-holes 1-5 have identical benches. It seems like eventually all the holes will?
Cons:
-the pro tee pad for hole 9 isn't textured the same as the rest. It can be very slippery.
-Poison ivy on a few holes.
Other Thoughts:
$6 per day or $25 for a year pass. I wasn't sure if this was a pro or a con. On one hand it keeps out some of the people who trash free courses, on the other hand you're losing $6.
If you are in the area stop by the CMU course. Comparing them will make Deerfield Park seem like the best course ever.
