Aaron Glantz met these Giants fans on his way in from work on the BART. The prize for the most committted goes to Rob Conway, a Giants' season ticket holder.
And lots of families too, here's one that Aaron talked to:
Afredo Sierra, center, with his wife and three year old daughter. A life long Giants' fan from San Francisco's Excelsior District, Sierra says he's not sure if his daughter will remember the parade but he still wants her to experience it. "This is historic," he said. "We've been waiting so many years for this."
