If one takes delivery of May Crude (in Cushing, OK by default) is it not possible just to store it there and redeliver against a short in June or do they make you get it out of there unless you already have a storage agreement with Enbridge or Enterprise? Or is it something else? Otherwise this seems too simple to collect $37k at delivery per contract, pay for a few weeks storage on site and redeliver it, collecting another $20k or so. Please enlighten me as to what I'm missing...
