At 13th and Princess, the other end of the block from Coleman’s house is where Leanie bikes back home from dance class at school, before then turning into Coleman’s front yard into the backyard. She is seen biking past these same three houses repeatedly (5 times, I counted), but from different angles to give the impression she is biking past several different houses.
Used several times throughout the film, initially it is where the gang originates from before they traipse through Coleman’s (Jason Robards) yard and flowerbed.
It’s actually behind the location for Coleman’s house, which is also right across from New Hanover High School, the school they attended. Most of the cast walked down this alley at one point in the movie.
