Communities from Oregon to South Carolina are preparing for an influx of visitors Aug. 21 — many of them pulling or driving RVs — to experience the first total solar eclipse to sweep across the U.S. in nearly 100 years. Some 12.2 million people in 14 states will be in the path of totality after the eclipse reaches the Continental United States between Portland and Salem, Ore., at 7:16 a.m. EDT, and concludes southeast of Colombia, S.C., at 2:48 p.m. Others to the north and south, in areas like Maine and south Texas, will see a 50% partial eclipse. The next total eclipse in the U.S. will occur in 2045, traversing from northern California to Florida.
