Hoghead515 Posted April 14, 2021 Share Posted April 14, 2021 (edited) 12th grade. Gonna go by the kids in the pic. They look like they are probably seniors in high school so I'm gonna say 12th grade.

Henri Charriere Posted April 14, 2021 Share Posted April 14, 2021 This is right up my, er, uh, alley. The steepest grade in Manhattan, Duffy's Hill on Lexington Avenue between East 102d and East 103 Streets, is 12.6%, and the car's hill appears steeper, but not by much. I do not believe it exceeds 15% [ Note: Filbert Street in San Francisco has a grade of 31.5%.] Link to comment Share on other sites More sharing options...
