Pros:
Very well thought out course, they used the park in an excellent way - avoiding crossover of the baseball diamond, basketball court and kids play area so it should be safe to play most the time beside pedestrians. Nice yellow pro baskets installed. They have one hard uphill shot but a couple really nice downhills, well done. The place is very well maintained like most Simi Valley parks. It'll be difficult to lose a disc in most places. Free parking, free to play. Where to throw is nicely marked at each hole with a yellow flex-post. Definitely worth going to if you can but at 12 holes don't expect a full pro course. If I lived in Simi still I'd be here every day. every. single. day.
Cons:
I feel it's almost too left hand friendly, 9/10s the population is right handed after all - a challenge is good though. There will be other people still not used to disc golfers being around them - other sports and park goers. Would be nice to have distance and number basket on the t-off markers just to know, a couple do have the number so I don't get the inconsistency there.
Other Thoughts:
Makes me wish I lived in Simi Valley still.
