Go to the corner of Market & 2nd Streets...there you will find a Rand McNallyStore, you know maps, books, etc, very serious travel info...anyway ask for a copy of
Rand McNally' San Francisco Cross Street Directory. The Bible for serious Bike Messengers, Cabbies, and other Delivery type persons...never, leave home (your hotel, hostel, friends house etc) without it. Now you're ready to ROCK...SF unlike most American cities, is easy in terms of size to navigate, ( traffic permitting) by whichever means you choose...Apprx 49 m2, or 126.90 km2 in area...
