I bought many exciting garden plants today, but I'm not going to talk about them until I've got pictures. Mission Hills Nursery is like the crack pusher of gardening. Psst -- we've got poppies! Little tiny poppies! You have room for poppies, don't you? I also got tomato cages, because I actually have pots large enough to accommodate them this year. Related to the huge pots, I got four cubic feet of dirt, which is equivalent 113.27 liters of dirt. Did you know that the gram was originally defined as the mass of 1mL of water, and so a liter of water weighs one kilogram? And then there's this fabulous digression in the Wikipedia 'litre' article about why the abbreviation for liter is a capital L rather than lowercase, including the aside that "On some typewriters, particularly older ones, the unshifted L key had to be used to type the numeral 1." Now I suddenly want to learn about typewriters. xkcd is right about Wikipedia.
(The worst thing? That comic just reminded me that I wanted to look up the Tacoma Narrows Bridge on Wikipedia. I'd never seen the video of the collapse before Ken showed it to me a couple of days ago, and we were both appalled by my ignorance.)
