Don't call it "Frisco". Or "San Fran", either.
Frisco in Texas is all right.
FOR THE LOVE OF ALL THAT'S HOLY IT'S NOT FRISCO. The use of this phrase immediately identifies you as someone who is going to buy a sweatshirt at Fishermans Wharf because they only packed godforsaken shorts for their vacation here in August. You have just inadvertantly set on edge the teeth of anyone who might be driving from San Francisco and would be offering such rides. It's San Francisco. If you have a moderately adequate set of typing skills, it shouldn't take that long to type it properly. If you must abbreviate... and I see that you are from "NYC" so apparently its a biologic necessity.. then use SF, or SF Bay Area or as you said the Bay Area. I personally enjoy "People's Gay-public of Drugifornia".
In all seriousness, good luck on finding your ride. Shouldn't be too hard.
