I've been working out of Memphis for the last half-dozen-plus years; I know what you mean about the TN summers. And the people here are great, even most of the ones here in Memphis, a few nasty and crabby ones aside.
But oh yeah, it's pretty up in and around New Hampshire's White Mountains- the old Mountaineer passenger train run jointly by the Boston & Maine and Maine Central railroads ran through there until service ended in 1972.
But now the Conway Scenic Railroad is running passenger specials through the notch area again. And they took that boarded-up old Conway passenger station and restored it to the thing of beauty it once was. Yeah, that'd be a mighty pretty area to settle down in, even if you did miss out on Tennessee summers. But in return, you'd get those beautiful New Hampshire autumn sunsets....
