I've been a victim of my own self a time or two as well.  When you said "I don't really need it" coupled with "If crop prices go down" you had your answer.  And it's not IF crop prices go down, and you know that.  Let it go.  When corn is $4.50 in a year or two and you drive by that place you'll feel a-ok.  If somehow it stays up, you can say "well, at least I'm not in there doing it for nothing."  BUT, if it drops and you're holding the bag, it'll be hard to sleep.  Let it go.
