Someone overnight took action to passively impede and attack trail users trying to travel between Sandcastle and the South Side. At the part of the trail just downstream from Becks Run Rd. someone pulled a trash can into the middle of the trail (which I hit since it didn’t become visible to my headlight until the last second), and then a bit further downstream pulled a largish stone into the trail and completely blocked the trail with downed branches and tree limbs. I called 911 to report the trail blockage and it was light out by the time I gathered all the bits of my lights that came off my bike, so it should not be too dangerous at this point. I also am reporting to 311 since this is just within the city limits. But a warning to all trail users to watch out for unexpected obstructions in the trail because there are psychopathic people out there.
