Street 99% of the time now. I used to do a street/sidewalk hybrid due to where I used to live (faster/easier taking the sidewalk up the mile to the base than crossing morning traffic), but one morning I encountered an ear-phone wearing ped and in avoiding them ended up doing an endo and busting my front tyre to hell. Almost pure street after that. The only sidewalk I take is the one near the local CVS, because it leads to several contiguous parking lots that gets me back to my current place. It measures about 5' long.

That spot. I take the parking lots to the NW of it on the way to and from most times.
