I saw one total eclipse in my life. Traveled to Aruba. The most awesome thing I have ever witnessed as far as nature is concerned. Better than the 2 tornadoes I once saw on a tornado tour I went on. Tell your boss you want the day off. I know that Colebrook NH is planning on 30,000 people. If it looks like a nice day the interstates going north are going to be jammed so plan ahead. I live about 35 miles south of the path of totality. I know many of the back roads going north but of course will wait. If it there is a departing storm and it looks better in NY State we will just head that way the day before and sleep in the car if necessary.
You HAVE to be in the path of totality. Even if your location has a 99% partial eclipse that 1% screws it up. I heard an expression about a total solar eclipse regarding the path of totality. It is like almost being dead to really being dead.
