Yeah, that river was really neat, I think it was at least 45-degree slope, so more like a log flume or something. It would be extremely dangerous to slide down because it ends in a grated culvert going under the road which would not be a happy ending.
I really enjoyed that ride, I was shocked how much I saw in 3.3km.
Yikes, yeah - that would definitely be an abrupt and not at all fun ending to going down it. And I really enjoyed your ride too - especially since I didn't have to pedal. 😊
