Crockett and River Parks are both excellent parks. Something for everyone to enjoy. However, I rollerblade there and in the last three years the asphalt has become broken and very rough in spots. Also, the bridge at River Park is very, very rough and the trail just beyond the bridge parallel to the river. I find it more an more difficult to skate. At times the paths are crowded and it's often a decision whether to run someone down or take a dive in the area along the path to avoid a rough spot. I usually choose to bail, which results in cuts, abrasions and bruises. If you don't make it to the grass and subsequently scrap the asphalt, because of the roughness of the asphalt, the parts of your flesh that aren't covered with padding will get scrapped to the bone. Skaters beware!
Pros: Ambience is great
Cons: Trails are not wide enough, and very rough pavement, standing water on trails.
