It depends. Some of our roads are really crappy. But, comunting I only have one stretch of road that has a bike path - and I take the path everytime.
I find it ironic that the same people that complain about pedestrians on the paths are the same people that get all in a tissy when motorists complain about cyclists on the roads. The ugly truth is, we all get annoyed when someone is in our way - be it a cyclist in the road or a kid on the path.
I ride my bike to avoid road rage - I'm certainly not going to replace it with.. path paroxysm?
