Love to forget I posted for like six hours
Anyway, it's mostly forests and hills where I actually live, but I'm within a couple hours of the Blue Ridge Mountains, which is where I was at today. It's always ~15°F cooler up there and the trails are generally pretty shady. There's a ton of different parks up there, and most of them go up to whatever the nearest peak is for a view at the top. Pretty small as mountains go, but it's as good as it gets in the east US.
Of course, it's also pretty crowded depending on when you go. I've been trying to avoid the most popular places, but even that's kinda risky. A lot better on weekdays if you can.
