Let it Snow?

Last night's bedtime snuggles conversation:

MADELEINE: Mommy.  Isn't it STRANGE that it doesn't snow in San Francisco, but it snows in NEBRASKA?
ME: Why is that strange?
MADELEINE: I don't know.  It just sounds like it should snow in San Francisco, but not in Nebraska.
ME: Well, it doesn't really snow much in California.
MADELEINE: Wait.  San Francisco is a CITY?
ME: Yeah.  It's in California.
MADELEINE: It is??
ME: San Francisco is a city, and Nebraska is a state.
MADELEINE: But doesn't Nebraska seem like it SHOULDN'T get snow?
ME: It can get really cold in Nebraska.
MADELEINE: But Nebraska has, like, lots of COWS and animals and all these farms.
ME: Well, Nebraska has a lot of farmland.  So in the winter, when the snow covers the farm area, it helps moisten the soil, so that in the spring the crops can grow.  Crops don't grow as well in really dry, hot areas, so-
MADELEINE: Mommy?  I'm not really very interested in learning about FARMS.
ME: Oh.  But-
MADELEINE: I'm more interested in learning about, like, Pilgrims and Native Americans.
ME: Well, farming has a lot to do with the story of Pilgrims and Native Americans.
MADELEINE: No, I mean, like, learning about their HOUSES, and what it was like on the BOAT, and in the tee-pees, and stuff.


Sheesh.  Okay.  I guess I'll just shut up about the farms already.
