This post will focus on a spot that is shown in the second Back to the Future movie (my favorite). When Marty and Doc head to 2015 (which isn't too far away from present time) they run into some trouble. Marty falls victim to greed and purchases a Sports Almanac that documents the scores for all sporting events from 1950-2000. This would give him the winners that he could bet on and make mucho dinero. He buys this almanac from a retro shop in 2015 and plans to take it back to 1985 and reap the benefits for another 15 years. Instead, Doc Brown spots the almanac and talks Marty out of taking it back to 1985 because he "didn't invent the time machine to win at gambling" he "invented the time machine to travel through time."
Marty and Doc encounter this reality when they head back to 1985. Marty wanders aimlessly through this Hill Valley nightmare and stumbles upon a current newspaper on a porch. Turns out, this porch belongs to the former Hill Valley High School principal Mr. Strickland. When Mr. Strickland pulls a shotgun on Marty, Marty tries to explain that he knows him from school. However, we soon find out that the "school burned down six years ago."
Mr. Strickland's house is located down the street from Whittier High (aka Hill Valley High School) at:
12511 Bailey Street
