After Danielle got back from the UP we had to wash Roxie because she smelled like a mix of dog and lake. Following that I washed a few days of riding of mud off my bike, during which time I noticed that the coiled green plastic hose I have has a small split in it. This causes a very small, powerful jet of water to spray out.
I’m not sure how it happened, but thankfully it’s still small. Hopefully it won’t get much bigger.
