Pros:
Hanscom combines factors unimaginable for most city park 9ers. Elevation, gaps, ceilings, risk/reward, you name it. Add to this tee signs to gauge your distance and turf tee pads and you have a full set of basic course amenities apart from benches. Even the baskets, while nondescript, are plenty serviceable and easy to see with the silver coat of paint. You'll be challenged and satisfied and probably want a second go-round.
Combining multiple challenges is the biggest strong suit of the course. Hole 1 has rising elevation, but a tree ceiling to get under. Hole 5 requires hitting a line, but also control to not go over the edge of the berm down to hole 6.
Elevation overall is superbly used, 1 and 3 are slowly uphill all the way, 4 and 7 are sharp downhills with ace potential (I hit metal on both) but also risk of going far too long or snagging an early tree, 8's basket is perched to the left about 10ft above the rest of the fairway up a small rise, and 9 is a blind basket over a rise.
Tree gaps and tunnels abound. Hole 2 has a left and right route that will need some good ground action to park the pin, Hole 5 has an obvious left gap but also a thin right side skip gap, just to add onto the risk/reward factor, Hole 6 is the best-looking hole on the course, 75ft tall trees on your left and right, a fallen tree blocking the fairway to go over or under. Then Hole 7 is a tight tunnel (12ft wide, if that) with one solitary tree trunk set about 40ft in front of the pin. Some sort of short flex is nigh on required to get a birdie.
Replayability is very high with multiple routes on every hole except 3, 4, and 8, and with the distances being so reachable it encourages different styles if you go for a second playthrough.
Cons:
It is possible for a disc to zip into the fairway of 6 from holes 2 and 5 due to it being in a small ravine between the two.
Blind baskets on 5, 6, 8, and 9 make a first-time playthrough a little more difficult than it should be. But that issue goes away after one round
Other Thoughts:
While the lack of distance may be disappointing for some, I find that it adds the potential for more creative shots since most holes were well within my backhand range (FH dominant, here) and if there'd been a little more time I would have gone for a backhand only round.
If you're in Omaha, this is the course I would recommend above all others. The fun factor is off the charts. The challenges, while not extreme, vary greatly throughout the park. This gets my #1 spot of 9-Hole courses I've played thus far, and I believe it will retain that spot for a very long time.
