OK, after 2 or 3 days, the prices being reported on Gas Buddy for my area of Northern Virginia are once again matching what the station signs are actually showing.
Still not sure what that was about, but I did notice the same user names reporting the higher prices for multiple stations.
Prices have gone up 5 to 10 cents a gallon over the past few days, though, but nothing near approaching the $4+ prices that were being reported in the wake of Donald Trump's invasion of Ukraine. Thank God we have Brandon in charge!
