Ray and Maize,

I appreciate you guys trying to educate us on capturing the carry.  For some reason, I struggle to understand how this is going to work out.  If we purchase the Dec, sell the July at 28, what would be the plan in less than a month (depending on your broker I assume) for the Dec?  Roll into March which is trading at +12ish to Dec?  Or just remain short July only?  I guess I don't understand how with the roll looming shortly and March trading at such a premium to Dec, and effectively loosing that on the roll and leaving us only about 16 can be much benefit....what am I missing?  Thanks guys!
