depends on what you want for the pictures. some places where i feel inspired to photograph are in the woods, near a body of water, in a field, nature-y things.
if you're more into urban places an alley would be good, as just a nearby city. maybe under a bridge or overpass.
this also depends on whether or not you want people or a person in the shots. i like shooting nature-y shots with one or sometimes two people in them.
