Ask Mr. Answer Person: "Why are gas prices higher in Decorah?"

Dave e-mails: "I drive from Decorah to my business in the Council Bluffs/Omaha area a couple times a month.  After a recent trip I noticed virtually every city I passed through had cheaper fuel than Decorah.  I noticed Preston, MN was 14 cents cheaper than Decorah.  New Hampton is 10 cents cheaper. A few months ago I told the manager at Kwik Star I was going to write a letter to the editor, locally, questioning Decorah's costly fuels and within two hours the price dropped 8 to 10 cents.  I think we're being "had"."

Mr. Answer Person says, "On Sunday I spent 8 cents a gallon less when I gassed up in Waukon.

Mr. A.P. has tackled this question before--and never gotten an answer.  Readers, do you have any ideas?
