If placed along a highway, a bluebird house should open parallel to, or away from, the road so the birds will not be hit entering or leaving their nests.

These practices help keep bacteria out, retain moisture, and prevent leftovers from picking up odors from other food in the refrigerator. Immediately refrigerate or freeze the wrapped leftovers for rapid cooling. Leftovers can be kept in the refrigerator for 3 to 4 days or frozen for 3 to 4 months. Although safe indefinitely, frozen leftovers can lose moisture and flavor when stored for longer times in the freezer. Safe ways to thaw leftovers include the refrigerator, cold water and the microwave oven.
