Does anyone have location suggestions for an engagement photo shoot in the East Bay Area (Martinez, Concord, Walnut Creek, etc. -- possibly outwards towards Pleasanton or Berkely if neccessary)? We are looking for a nice fall location for around Thanksgiving time. I know Briones (martinez), Mt. Diablo and Tilden Park.. Any others out there? I love nature, so pretty much any outdoors is great. Not sure what other elements I'm looking for. Suggestions welcome!
