Canal Halfpipe/metal boxes

there's a lil' section of the canal that's paved like a halfpipe, but it never goes completly vertical. it's more like 2 banks with some transition between them and the flat, but it's still hella fun. Then if you go west past the canal there's a bunch of metal box things, no clue what they're used for except for skating. one sticks out past the other two that are next to it, so you can grind it, and another has enough room in front of it so that you can get speed to manual it. there's also a pretty good concrete ledge. all the ledges are short, but they're still cool. there's also a flatground gap that's fun to do when you get bored.
