Pros:
I don't normally put a preface before my review, since it isn't a "Pro" but this is the first thing you read, and I wanted to explain where I'm coming from on this one - Johnny Roberts is designed to be a pitch-'n'-putt ace run kind of place. It's not the kind of course where you're going to find long bombers, to wit, they even have the Johnny Roberts Challenge, which is using just a putter on the whole course. That said, I've tried to rate it based on what it is, not what it isn't.
+ Great baskets, tees, and signage
+ Navigates like a breeze, plays a loop
+ Situated on some impeccably manicured land, super low chance of losing a disc here
+ Decent amount of parking and port-o-johns on site
+ Great for beginners, family-friendly, a place to hone your short game and bump up your number of birdies/aces
+ Multiple pins
Cons:
- Cramped; has serious potential for crossing fairways
- Crowded; not only w/ other players but other park patrons - with the short hole setup it can get a little dodgy
- No teeside benches, not many trash cans around either
- Dearth of variety in distances and shots required, overall challenge is on the low side, even w/ putters only
Other Thoughts:
I'd recommend Johnny Roberts to anyone at least to play once for the experience. The Putter-Only challenge adds some flavor to the round, I'd highly suggest trying it out, plus, it's not like you really need those mids here, much less drivers - lighten the bag up for this one.
It was a little on the crowded side when I played, but I didn't have much issue with it. It definitely isn't going to let you air anything out so if you're in love with long bombers, check that at the parking lot or try elsewhere. It's just a fun, short course that stands out as a novelty. Destination-worthy? I don't know. It's definitely unique and can be a lot of fun if you know what you're in for. Would I play it again? Totally. It's a nice complement to Bird's Nest nearby where you can really air your arm out.
