Pros:
Lots of variety to be found on this course, some really tight shots, some open ones, all of your shots will come in handy to shoot a decent score. Some good risk reward situations where going for it will either pay off nicely or leave you scrambling for a bogey. Offers more length than the Earlewood course across town. Some decent use of terrain with one particulary nice uphill shot and a fast downhill green. Decent tee-signs help you figure out where to go, and a detailed map is provided online. Teepads, while dirt are generally in pretty good condition.
Cons:
Even with a map I would consider this course hard to navigate, although I think they made some changes so it would flow better than before. More than a few really tight fairways that could frustrate the beginner and the experienced player. You will hit your fair share of trees.
The course plays in the woods around a series of soccer fields, so particularly during the weekends the park can be extremely crowded. It also isn't in the best of neighborhoods, but with a little common sense you should be fine. Dirt teepads.
Other Thoughts:
I thought that this was a fun course to play, given what it offers. It is a good contrast to the other course in Columbia with its added length. If you only have time to play one course I would say Earlewood, but Owens shouldn't be disregarded. You'd save time by printing off the map, and even more time by going with a local.
