This is a pretty cool new phone app — a field guide to golden gate park — developed by the Academy of Sciences.  It’s interactive, so users can help build a data base on plants, wildlife and other things of note in the park.  It’s geared more towards the natural than the cultural side of the park, but with some history and cultural information thrown in.  We’ll be keeping an eye on this, to see how it grows!
