New Hampshire didn't just name its tallest mountain after the first President, then went on to name the next several tallest mountains after subsequent presidents.
Fortunately they decided to stop after a while, it'd be silly to have Mt Eisenhower or Mt Bush. Or two Mt Bushes.

For the record, there is not, nor has there ever been, a Mt Reagan.

This view is looking south from the Cog Railway as it heads down back to base.
