As you can see from picture 1 this is a Tier 1 park which is all about insurance, and not about fun. (quote below from Minneapolis Parks Dept. web site)
At this time, the MPRB is developing only Tier 1 skate parks, which have equipment no higher that 48 inches and attract no more liability than other park facilities such as playgrounds, ball fields, or wading pools.
A tier 1 designation seems like it should be the kiss of death, but still there were guys here who session it every day (weather permitting I assume) and seemed to be having fun with the pyramid, the rail, and flying out of the little, tiny, 1/4 pipe/launcher obstacle. One of us still managed to crush a finger pretty good (photo on request) so obviously something has been done right, but it is precious little.
My verdict: Absolutely not worth special trip. If you are killing time and need to skate while your little sister is at a birthday party then by all means check it out.
