Depending on where you ride here, you often meet either inebriated pedestrians or cyclists. I usually hope they are where I can get off the bike path and pass them on the grass. The bell or "passing you on your left," doesn't do a bit of good. They're completely unpredictable and oblivious.
The other night I came upon a family who had left the bike path to look at something in the creek. They left their bikes and burley on the path, effectively blocking the whole thing. Sigh.
