Prices seem to be leveling off and dropping in this part of the midwest.
I drove down I-35 in Minnesota yesterday and saw $2.89 for regular in Owatonna MN, and $2.99 in some other spots.
Since I was getting low, I paid $3.07 at the Casey's in Minden IA along I-80, but that was a touch high for the area, as a number of stations in Omaha are in the $2.80s and $2.90s (if I could've made it a few dozen more miles I could have paid $2.85 or so), down a dime or two in the past week or two.
We're still well under a dollar cheaper than the peak we've paid here (well over $4 for regular), and prices were in this ballpark in 2018 (the $2.90s), as E365 mentioned. I think the trend is good and downward, but current prices here are not unreasonable and are lower than in recent memory.
