I love how, in this part of California, a neighborhood can happily contain Washingtonia palms (native to southern California's desert oases), coast redwood (native to the coast from Big Sur to slightly into Oregon), citrus, stone fruit, persimmon, and wild nearby, all the bay laurel and California oaks and endemic California sycamore and walnut and big leaf maple and chaparral plants that have been so well preserved in this less eucalyptusy corner of the bay area.
I collect natural history, environmental, and geography books, almost compulsively. I look for used versions where I can (to save paper) but also appreciate that many of these books come out in runs of a few thousand copies, and aren't profit-makers for the publishing companies, so when they come out new, I buy them while they're new. If you like Geographile and want to let me know, please either comment on my posts, or visit my Powell's wishlist to feed my book collection. You might find books you like there, too.
