Pros:
Baskets are nice and the grounds of the school/playground are fairly well kept. Decent place to introduce the sport to someone and toss a round with a loved one for recreation. A better-than-nothing place to keep your mid-range game sharp while visiting historical Fredericksburg.
Cons:
Not at all challenging for advanced players. Not marked and does not have tee pads. Lacking distance and variety.
Other Thoughts:
If you're in town visiting, bring your discs along and play this course. It will probably be the most enjoyable 30 minute activity you'll do in Fredericksburg. At least you can add another notch on your 'courses played' list.
