I used to think these were a good idea until I went on a road trip and tried them out. They are fun for what they are but as others have mentioned, a bit limited. Now I've sort of 180'd on the idea of "flow" as a good design concept for skate parks. I think you actually want different areas spread out where skater of different ability or just different terrain preference can practice stuff without getting in the way of everyone else.
IMO some of the biggest bummer new parks aren't Evergreen, but the ones where they combine "flow" ideas with regular obstacles. It doesn't work to have guys bailing the ledge/hubba right into the path all the scooter kids are zipping through
skatepark designer should start making containment zones for the scooters. like put the pump track and fly out off to the side, completely cut off from the ledge area, etc
lastly I don't think some of the counter argument consider the political reality of parks like this. like telling the kid to just go skate street or build their own. most of these are going up in small towns where there's no spots and small towns are pretty anti skateboarding. getting a park usually mean skateboarding is now banned everywhere else, and by the way we're also going to destroy the DIY spot at the old basketball court. so its the moon park or nothing. you better like it kid or else, we spent a lot of (Jeff Ament's) money on you ungrateful skate boarders...
To be honest I get your point, and being from Europe it's even more true, but for example, we had our park renewed and basically almost sucked more than the previous one.
This created a divide, between who was very into it, and started skating more other skateparks around (getting on a train or driving around) or just by hitting streets or making diy spots (not parks) and the kids who wanted a better park and eventually stopped skateboarding.
My whole point is, unless you are involved 100% in the skatepark design process (and even that is still sometimes a bummer) you shouldn't be that concerned, because no-one is gonna go out of its way to ask you what you want to skate.
Sometimes park builders have to listen to the town, sometimes the local shop, sometimes the scooter kids, this way you end up having a public skatepark. It need to be suitable for everybody, so here's the problem.
Has anyone skated a "perfect park"?
