I feel the oil bubble is near. What are my investment options outside of “shorting futures contracts”?

This is sort of ” off the wall”, but if you think about it it makes sense: buy into some ” refiners”..if the price of a barrel of oil comes down, then the margins between buying the oil and producing fuels ( gas and diesel) goes up….and if it happens to coincide with the peak driving season, the refiners should do well.
