Note that when you go to the original page, and do the traditional xkcd mouseover for minor punchline in the alt text, you get the tidbit that Uzbekistan is one of only two doubly landlocked countries. Before I look it up, I have to figure out what the other one is.
Now I want to get a blank map, with only coast lines, not borders, and fill it in like this. I can put about 2/3 of Africa and nearly all of South America. Eastern Europe and what my husband calls "Soviet Blockistan," or the parts of Asia and Europe that were formerly Soviet Union countries, are a lot harder.
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.
