Pros:
Flat, good for putting practice as the course is probably going to have pedestrians all over it. Quiet place. Perfect to start a child on or if you live nearby it would be great to have access to all the time. Honestly this is a great park just to expose more people to disc golf, then they'll realize there are some awesome courses close-by (looking at you Sequoia, just down the road, Rabbit Flats T.O., and Veterans Park Sylmar.) Good luck losing your disc here *it's close to impossible.
Cons:
Small, based around a jogging path and as a neighborhood park you should definitely be respectful and wait until it's clear. Hard to find starting positions on a number of holes, not well delineated. Mandatories also not clearly marked so we reinforced what we thought before we threw.
Other Thoughts:
I would definitely rather this place exist than not.
