Pros:
Awesome course. Great use of elevation changes, great mix of hole styles and lengths. Wickham has exactly what I'm looking for in a well-designed course. First, there are many difficult holes that make you work for pars (while not being so difficult that a par is impossible), combined with many holes that present very reasonable birdie opportunities (while not being 'gimmes'). This makes for a challenging, yet rewarding round of golf. And second, the approximately 50/50 mix of wooded/open holes is excellent, and most of them utilize the constant elevation changes in the park to create even more diversity of holes.
Shorter Rec tees are available on some of the longer holes, which is always nice to promote amateur play. These appear on holes 1, 3, 6, 8 and 11 (but not 7, to my wife's dismay)
Baskets and tee pads are excellent, with tee signs at every hole, offering all the juicy info you need (preferred route, distance, elevation change, par, etc).
Cons:
Not too many, and they're mostly picking nits. If the grass hasn't been mowed on hole 1, there is potential to lose a disc, but you can always play the rec tee to avoid that hazard. On busy days (weekends, holidays), it can be a little tricky playing the course with all the pedestrians/sunbathers/picnickers using the park. If you haven't played the course before and aren't carrying a map with you, finding some of the next tees could be very challenging, particularly 12, 13 & 17. Bring a course map with you! And of course, the biggest con is that the course closes down and they pull the baskets in the winter (November through March).
Other Thoughts:
There are permanent alternate baskets on holes 2, 7 & 9, with an alternate tee for 8. There are also an additional 4 holes (A,B,C & D) sandwiched between holes 5 & 6. After finishing hole 5, take a left and walk up 6's fairway. The tee for hole A will be in the woods on the right.
The park itself is very nice, with many other attractions, including numerous gardens, children's playgrounds, athletic fields, and a cool little aviary between holes 11 & 12. Great views of the Hartford skyline from hole 7's fairway.
