What are diesel prices in your area?

I have been noticing that the price I am paying for diesel these days has jumped about 60 cent per gallon. I drive by places that are charging $3.69 on the high side to $3.41 on the low end. Just 3 weeks ago I filled up for $2.98 the other day It cost me $3.41 and I think this station was just slow in rising its price because the one down the street was $3.61 the same night.
I am in the Chicago land area so I would expect my prices to be higher, but am wondering what other people are pay in their area?
