Evergreen ones are nice for ugly winter landscapes that need something alive. Some extra flowers can be a nice touch. Stop by a local nursery. They will likely let you return them when you are done.
Other minor landscape modifying tools like tape, string and pruning shears (with permission) are nice. Some folks will actually welcome a yard cleanup in return for using their house. A nice print for them is usually appreciated.
Water down a drive way or side walk. It will reflect light and help rid the scene of a big colorless area.
Sheets of neutral density film can be useful. Cut to shape, they can dim lights you have no control over, like street lights. May need a ladder.[/font]
