Pros:
Relatively short drive from all of the eateries and shopping in Frederick. Lots of other nice facilities on site (Walking trail, soccer, ball golf course, playground equipment, etc.).
Practice basket on site near tee #1. And there are two "bonus" holes, #19-20, available. (See Swatso's review for details.)
I had two excellent hosts when I played, which made navigation a breeze. However, if you don't have the benefit of such gracious hosts, the course is pretty self explanatory once you find #1 anyway. And the map makes things even easier.
Two sets of excellent black-top tees, clearly identifiable with wood posts painted red or blue on top with hole numbers. The tees were big enough with good grip. They are also level to the ground, so even if you need a bigger run-up, you could have one. The flags on the pins are the biggest I've seen and are extra helpful on the back 9 where some pins are close together.
Nice variety of holes... on the front 9 especially. There's not a lot of elevation change available, but the course takes advantage of it where it can. Holes 3-8 really make you think about hitting a good line and each can be played with several different tee shots. You can get creative on these holes with anhyzers, hyzer-flips, overhand shots, etc.
And even though the back 9 holes are really open, the pin placements help keep it interesting. Several pins are close to the edge of a hill. This make roll-aways a serious possibility and puts a premium on accurate approaches. Plus a couple are close to OB areas, again, making accuracy very important.
From the blue tees, there are 7 holes over 375' so there should be enough distance to keep many players' needs for Big D satisfied.
Cons:
The nature of the property itself causes about half of the holes to be almost completely open, just playing over lightly rolling, grassy hills. If this course were just about holes 10-18, it would be a big disappointment to anyone other than the complete novice. And it might not encourage the novice to keep playing, either.
When I played, it was January and the park was empty other than the group I was playing in. So I didn't experience any issues with people interfering with the course. I can see, though, that it could be an issue as holes 3-11 basically parallel a walking path. And the soccer goals on hole #1 make for interesting obstacles, as long as there's nobody playing soccer.
Other Thoughts:
Considering its' shortcomings, this course is a lot of fun. Here are my highlights.
Hole #2, as simple and straightforward as it is, is made interesting by a dug-out/drop-off area just to the left of the pin. Stay above the pin and you may have a good birdie opp. Fall over the edge, though, and you'll be working for your par.
#3 plays down-hill to a nicely protected pin, surrounded by evergreen trees and having other trees in the fairway. Don't go long or right, though, or you're OB in a hurry.
#6 is a great right turning, down hill shot. It's protected by OB short of the "green" area. If you go too far right, or end up short, you're OB in the adjacent farmland.
#7 is a fun, "across the valley" shot, playing to a pin nestled in behind a big row of mature trees.
#13 would be a pretty uneventful, straight-forward hole, if not for the backdrop of the old red barn immediately behind the pin along with the drop-off created by the driveway "ramp" running up to the barn. It's just a simple, but pretty hole.
And bonus hole #19 is a great disc golf hole... Long, tight, low ceiling and mean.
As mentioned in my title, I will definitely be back to play Heritage again. I look forward to getting the play the long tees when the weather is better. It's not a great course, but it's definitely worth checking out. And it does have a few outstanding, individual holes.
