Get permission: Before you start setting up, check to make sure that your brilliant idea is actually permittable. Run the idea by your neighbors to find out if they have concerns about noise levels at night (and if they’d like to attend the screening). The last thing you want is the police knocking on your door right when you’ve gotten to the good part of the movie.
Consider the space: Where will you be projecting the show? Your driveway is a great option because it provides a level surface for equipment and is likely close to a power source in the garage. Otherwise, look for a flat surface anywhere around your home. If you’re putting the screen in the backyard, you’ll likely need a lengthy, heavy-duty extension cord, and a power strip.
