The Beach Chalet, with breathtaking Depression-era art downstairs, and fabulous burgers, beer, and ocean view upstairs, is probably one of the least well known of San Francisco's most wonderful places. It's in the northwest corner of Golden Gate Park, across the Great Highway from the beach. When you visit, I will take you there.
Before my sister died, this was on the list of places she wanted to go again. I'd never been, had no idea it was there despite years of hanging out (and a few months of living in) San Francisco. Now, it has emotional value for its art, as well as having been the last place I had a coherent conversation with my sister. (Brain cancer sucks.)

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.
