How about we… Go see the Monford Park Players do Shakespeare.
How about we… check out how our favorite animals are keeping cool at the zoo.
How about we… play tennis, see a subtitled art house movie, & eat lobster -- a la Annie Hall. http://bit.ly/anniehalldate.
An awesome place I've visited:
Skinny Dip Falls off the Parkway is a stream running through a tight, very mossy chasm, with wonderful little pools of clean, cold water. It looks like a fairy land to me.
My perfect Sunday:
Hiking to a waterfall or floating in the lake with great friends.
