Progressive Pumptracks makes modular pump tracks from three different materials, wood, steel, and concrete. The wooden ones seem like they would have a short useful lifespan for a skateboard, even though they are covered with a composite surface. The concrete version looks pretty fun though, although technically still reconfigurable, in reality it seems like it would be really hard to move without a good forklift, maybe two.
It’s a pretty exciting idea until you realize that ARC is the company behind it. Actually, it’s still a pretty cool idea, just hard to swallow considering who makes them. A pump track is not really a “skatepark” but more like a skatespot. It looks super fun, and I love the idea of plopping these down on a disused tennis court.
