I have a house in a major US City with a 3rd-floor outdoor deck that also allows access to the roof. These areas provide my only outdoor areas and excellent views of the city skyline, and thus are ideal for entertaining. The deck is small (about 10′ x10′), has an outdoor light, and has one outlet. The roof has no electrical outlets or lighting. I am trying to find ways, preferably permanent, to light and provide music to these spaces. Also I am a college student on a very tight budget so the cheaper the better. Any and all suggestions are appreciated.
