Is there a split on stroller parents and babywearing parents, or do we alternate based on activity?

I strongly prefer babywearing because I have nightmares of pushing the stroller out in traffic before me. My husband prefers babywearing (though he was in the stroller camp before DS was born) because the stroller stresses him out.

Only one of my other friends in this area (mildy hilly suburbs) is a baby wearer.

Which are you, or do you do both? Why do you prefer that one?
