If you like historical maps as much as I do, this is pretty wonderful. I'd always heard that there used to be a bunch of airports up and down the San Francisco Peninsula. Now I can see where they were: Bay Meadows, San Mateo, Belmont, Cooley (a private airport north of San Carlos), downtown Mountain View, and a seaplane base by the San Mateo Bridge: http://ims.er.usgs.gov/gda_services/download?item_id=5506677&quad=San%20Francisco&state=CA&grid=1X2&series=Map%20GeoPDF http://ims.er.usgs.gov/gda_services/download?item_id=5506677... The circles that look like gears are airports. If this gets your curiosity going like it did mine, this site has more about these airports: http://www.airfields-freeman.com/CA/Airfields_CA_SanJose.htm http://www.airfields-freeman.com/CA/Airfields_CA_SanJose.htm And if you're around Palo Alto, did you know that Hawthorne Avenue, three blocks north of University, used to be a railroad spur leading to the Catholic University (now St. Patrick's Seminary)? http://ims.er.usgs.gov/gda_services/download?item_id=5503465&quad=Palto%20Alto&state=CA&grid=15X15&series=Map%20GeoPDF http://ims.er.usgs.gov/gda_services/download?item_id=5503465...
