Gas here in Ontario where I live is $1.21/litre which equals about $5.49/gallon. We live in a "border town" area, so I do not gas up in Canada...I gas up in Baudette, Minnesota, which at this time is selling for $3.19/gallon.
I made a trip to southern Minnesota yesterday, and the lowest I saw it listed at was for $2.79/gallon. I never saw any for higher than the $3.19.
These prices are all for regular unleaded gasoline.
