I'm in Northern New York and haven't had had or seen any issues....87 is up to $3.05 most places.
Fill up in Ohio about three or four exits BEFORE you cross out: that's where it's cheapest. Fuel in the NY Thruway is easily .30 a gallon more than anywhere else.
Expect about $40. in Tolls to be mailed to you from traversing the NYS Thruway, and Mass has tolls too, just not broken off in your ass like NY. IF you can get a "E-Z Pass" before you leave, that's the way to save some money.

IF you're carrying a Handgun through NY, keep it unloaded and secured in a hard case, and if stopped, do not volunteer any information, consent to a search, or stop here unless necessary. If you need to fill up again, and I suggest you do, get off at I-81 in Syracuse: there are stations a mile or two off the Ramps as well as Food, pee-stops, etc. There is a Cabella's in Buffalo that's OK to stop at and gasoline there are normal prices. past that, there are places all along the way, again a few miles off the Ramps (except in a few rural exits were there's literally NOTHING) Use your Map/Points of Interest function.
I expect there are thousands that pass through carrying a loaded handgun without issue, but if the Purple Tie Mafia get wind you've got a handgun, you ARE going to have a bad day.
