Hill Valley

Hill Valley is where Doc Brown raps in Epic Rap Battles of History 24. The exact part of the town is the courthouse/clock tower. The DeLeorean time machine appears in the background as well.

Information on the location
Hill Valley is the hometown of Marty McFly and Doc Brown, as well as the main location of the movies. In the movies, we've also seen past, future and alternate versions of the town. One of the most known places in the town is Courthouse Square, with the main buildings being the courthouse/clock tower, wich plays an important part in the first movie. The clock in the tower is struck by lightning in 1955, resulting in the clock standing still from then. The strike also generated the 1.21 gigawatts needed for the DeLorean to time travel.

Information on the DeLorean
The Delorean is a time machine build by Doc Brown out of a DeLorean DMC-12 and it's his most successfull invention. It's a plutonium-powered car. It needs 1.21 gigawatts of energy (either created by a nuclear reaction or a bolt of lightning), and it needs to hit 88 miles per hours in order to time travel. In a later stadium, the DeLorean was also able to fly. It is destroyed in the end of the third movie.
