I'm sorry about the short notice, but I just found out about this.
White House Farmer
I've been thinking about double-digging part of my yard and installing more food plants this year, so when I saw that President Obama was considering the same thing, I thought that was pretty wonderful.
Go vote for one of the farmers now, as the voting ends tonight. Then think about what you might grow to eat this year. Even if it's just a tomato plant, you're becoming part of the solution.
