Pros:
Best course in Toledo area (south of the border at least, I haven't' tried any of the courses just into Michigan)
Heavily wooded compared to Carter Park or Woodland Park.
Multiple Concrete tees for each hole.
Easy access from all parts of Toledo
Baskets in decent shape
Multi-use park so there's stuff to keep the kiddies busy while you disc (if you have kids of course)
Strong police presence, which is good, because...
Cons:
the neighborhood isn't that bad, but it's not great.
The course is nothing special
Navigation can be challenging.
Several holes play too close to roads for comfort.
Other Thoughts:
Ottawa Hills is my least favorite course I've played in Northwest Ohio, even though I've rated it higher than Carter Park. The neighborhood has everything to do with why I won't be back to this course. First off, it really is NOT that bad a neighborhood, but when my other options are in very safe suburbs and more importantly have positive memories for me (Carter Park was where I learned disc golf, and Woodland Park is set up in the park in front of my old elementary school) why take chances with playing a course in a somewhat rough neighborhood that isn't that much better than the competition?
With that said, technically Ottawa Park is the best course between Bowling Green and the Michigan line. It is the most heavily wooded and has multiple tees, which both Woodland and Carter lack. 12 years ago I used to not like Ottawa Park because it was much harder than Carter, and didn't cater to my game. Now I don't care for it because it doesn't compare to the courses I regularly play in Michigan (Deerfield and the Vines) or the courses I play in Columbus (Simsbury, Hoover, and Alum Creek). But comparing Ottawa Park to it's direct competition within a half hour drive of my parents house in Perrysburg it is still the best course Toledo has to offer.
Don't let the people talking about how rough the neighborhood is scare you off from trying the course. I've never been bothered while playing, although there is the occasional character walking by.
