Cool Tool for What's Fresh

I came across this cool tool while reading Filmore Containers blog (via Food In Jars blog).

WhenSeason tells you what’s in season in your neck of the woods.  Select your state and the month.

This has me wondering if there’s a garden planning tool out there that would let me input a list of crops and my zip code.  The result would be a schedule for when to plant each crop.  Hmm I better learn how to code.
