I've seen calls for $10.00 oil. Seems far fetched, but $100.00 plus seemed completely unreasonable for oil a few years back. One thing for certain with futures is that they always go higher than you think and they always go lower than you expect, so anything's possible. Just trade what you see and go with the "flow"! 
If the global slow down continues at the pace we have seen recently, $10.00 is doable. I doubt we go that low, but I'm pulling for it to happen. It would be nice to buy diesel in the US below $1 per gallon again.
