We have MUP's all over the place around here to the point that I don't ride in the street any more . In Long Beach Ca.one of my favorite trails has a path for wheels and a path for walkers . I have had some interaction with clueless people though . One time I came up on this lady , I was going pretty fast and I couldn't see her in tell the last 30' she was just standing there looking up at the sun with arms out stretched . So I yelled bike , she jumped about 3' off the ground by the time I passed her we were both laughing .
