Walt Whitman is buried across the street from my nursing school in a lovely, wooded old cemetery. For 33 months, I had that lovely place to look at from my window. Eventually, I drove into the cemetery to find his spot, tucked into a hill. I couldn't see his grave from my window, or even any specific grave @ all, but it was great to take a break, sit in the window seat, and just look out @ the pretty trees and greenery.
