I use slightly more than 2 years ago.

Demand in the US has risen and will probably continue to do so.
Refining capacity in the US cannot keep up and hasn't been able to do so for many years.
We were able to import cheap gas and that kept the prices low and stable. The demand abroad has also increased to the point where we can no longer count on cheap imports.

Gas will dip down to around $2.70 this winter in Ca. (depending on hurricanes and how cold it gets, heating oil etc).
Next spring the refinery maintenance schedule is not supposed to be as severe as it was this year so the supply deficit shouldn't be as bad as it was this spring.
Next summer will probably see prices near $3.50 or possibly higher.

I sold all of my refining stocks about 2 months ago but plan to invest up to $3/4 mil into VLO and TSO again around December. I figure they will dip and then climb to near new records by June.
If the hurricane season is heavy or the winter is unusually cold everything changes.
