Could you explain the meaning of "On" in this sentence?
Reading a book, I bumped into this sentence.
"On a rainy afternoon she walked out of a doctor's appointment and hailed a cab on Central Park West in New York to get back to her office."
In this sentence, what does "on" mean?
1. Does it mean that she took a taxi in Central Park West, the place where she got on a taxi is Central Park West?
2. Does it mean that she took a taxi to Central Park West, where her company is located?
I am sorry for my poor English. I hope that I could make my question understood. ^^
