Marty then seeks out (the younger) 'Doc Brown'. First, he goes back to his garage/lab (above)
and then discovers the Doc's house is still standing in 1955 (below), and it turns out to be
(in real life) a very well-known Pasadena landmark: The Gamble House,
a 1908 Craftsman home designed by famed architects Greene & Greene.
It's located at 4 Westmoreland Place, in Pasadena, CA, and offers tours.

(The tours emphasize the architectural history of the house, not the movie.)

The Gamble House is located in the 300 block of N. Orange Grove Boulevard,
three blocks north of Colorado Boulevard (the street made famous by the Rose Parade).

(You'll find the Gamble House's official website at http://www.gamblehouse.org.)

So Marty tries to get fresh with his young mom in a car in the school parking lot, so that
his young dad can then 'rescue' her and play the hero. But his plan doesn't work out that well.
His mom turns out to be far less naive than Marty had thought, and the bully Biff ends up
locking Marty in the trunk of a car. Fortunately, his dad shows up and actually rescues his
mom from Biff, insuring their future union.

These scenes were also shot at Whittier High (12417 E Philadelphia Street, in Whittier),
but not in the parking lot. They were filmed at a part of the school we haven't seen before;
it's actually a grassy quad behind the main building, on the east side of the campus. In the movie,
they just parked the cars on the grass and the wide sidewalks to give the illusion of a parking lot.

And here are two photos from Steve Mynott of that side of the school, as seen in 2009:

Back inside the "Enchantment Under the Sea" dance, Marty watches as his parents
nt their budding relationship on the dance floor, then launches into a wild
version of Chuck Berry's "Johnny B. Goode" that shocks the dancers (and inspires
Chuck Berry's 1958 hit). This takes place upon the stage at the same
Hollywood United Methodist Church in Hollywood, (which in real life is
about 27 miles away from Whittier High School).

Finally, 'Doc Brown' figures out a way to send Marty "back to the future". Because the clock
atop the Courthouse stopped when it was hit by lightning in 1955, they know when it will be struck.
So Doc devises a plan to use the electricity from the lightning bolt to power the time-traveling
DeLorean back into 1985. This scene was shot, of course, back at 'Courthouse Square', which
is a large outdoor set you can see on the backlot tram tour at Universal Studios Hollywood.

Before the movie ends, we return to the Twin Pines Mall (for a reenactment of the original
shootout with the terrorists), then we end up back at Marty's house (where Marty discovers
the favorable changes he has accidentally brought about by tinkering with time travel), and the
time-traveling DeLorean roars off for the future over Marty's Street (in Arleta).
