NASA has stated that experiencing a total solar eclipse where you live happens about once in 375 years. While I thoroughly expect modern medicine to one day advance to where humans are living extremely long life spans I do not see myself catching the next one unless something changes drastically very soon.

There is no real guessing game when it comes to when the eclipse will pass. Per NASA you can set your clock to the exact moment it will pass. This projection shows

The lunar shadow first crosses the West Coast at 9:05 a.m. PDT. People in Lincoln City, Oregon, will be the first in the continental United States to see the total solar eclipse, beginning at 10:15 a.m. PDT.

A total solar eclipse can sometimes take as long as 7½ minutes. The longest eclipse duration for this event will occur in Carbondale, Illinois, and will clock in at two minutes, 43 seconds, beginning at 1:20 p.m. CDT.

Eventually, all good things must come to an end, and the lunar shadow will depart the East Coast at 4:09 p.m. EDT.
