Why Are Gas Prices Skyrocketing This Time?

Factual Questions

I track car expenses in a nice phone ap. The average price per gallon for me for the last few months in California has been:
December: $3.369
January: $3.276
February: $3.199
March: $3.224
April: $4.119

Definitely a painful rise upwards. Last year around this time I was paying $3.559/gallon.

Gasbuddy’s a app that essentially crowdsources gas prices. Basically you report the price at stations you pass, and then other app users can use the app to find the cheapest nearby gas based on those reports.
