Pros:
Dual tees most holes (except for newer nine).
4 pin placements per hole (except for newer nine)
A lot of excellent holes long to long; but, also opportunity for lesser players to play short tees. Pin placements moved often, to allow, again, for lesser players to play layouts suited to them; but, to keep better players interested.
27 holes (the newer nine is the area you should score well on; it is less tough than original; but this will probably be improved upon as the years go by; if continual course improvement here in the past is any indication of what is to come). There are a few good holes on the newer nine. (Many of these holes have been tourney holes for a long time).
Homemade aprons off the end of most tees. While these are not pretty; and could be considered slightly dangerous; due to being somewhat unlevel; they are better than a rutted hole in the ground.
Have I mentioned four pin placements?!! The course plays quite a bit different on every hole; depending on which pin is in the ground. Variety is a HUGE plus for a course that's been in the ground this long.
Elevation is used as well as it could have been; especially in long pin placements.
No signs on long tees; but short tees have signs that show all tee and pin placements, with footage. Homemade signs, but they do the job very well.
Cons:
This is definitely a well played, "city course." As with any big city, there are some mildly unsavory characters on this course at any given time. (Most vicious fight I've seen in my life occurred here, but don't want you to think this is the norm. All the same, you may not want to "call anyone out" at Dretzka!!)
The course is often crowded with all varieties of players; including big groups of families and recreational players.
Open greens to a large degree.
Not a lot of huge length; and some holes; depending on the pin placement, are quite plain.
Other Thoughts:
I believe the no wimps, no whiners, phrase originated here. This course hosted one of the biggest; and often, a pretty severe, ice bowl opportunity.
Though I don't think they're much involved in the club/tourney scene, anymore; Joe Weinshel and Ted Mani should be congratulated on what their vision for disc golf in Milwaukee has become. The high amount of traffic here; while a bit of a downer on one hand, is a testament to their vision, years ago.
The constant addition of pin placements has kept this course pretty up to date.
There are some who will find fault with me rating Brown Deer and Dretzka both with a four rating. Brown Deer LOOKS much nicer now; it is much newer (believe me, if you saw the original Brown Deer in the ground; it was more beat up than Dretzka is currently). There are more modern, high speed disc shots available at Brown Deer too. But, 27 holes (albeit the newer nine not being great), and the multiple pin placements; kept me from dropping this one to a 3.5.
I would point out that I think Brown Deer is probably an overall better experience. For instance, as we played, this last time, almost all Dretzka pins were in short placement. We played a round from long tees (which was challenging) and a round from short tees. Short to short is a birdie festival....which you will not find at Brown Deer. But, is this really a con... for the family crew? Multiple options is a plus in my book....
I also believe there is a set of gold tees only used for tourney play; to keep open players interested.
