escape, grass, reeds, not sure

Well Maeve and I wanted to get out of the city yesterday so we just started driving north until we decided we would go to the beach and get off the interstate in a town I was vaguely familiar with. I told her about how there used to be a big abandoned mental hospital there that was demolished a few years ago. I told her there used to be patient graveyards, and I wonder if they are still intact, though it would be almost impossible for me to remember where they were since it had been about five years since I went to that place.
Just as I finished telling her all that, I noticed an area that looked familiar. We drove further into a complex of buildings to investigate, and I was beginning to think that this was the spot where I had parked and gone through the woods to the old hospital campus years ago when the buildings were still there. So Maeve and I parked, climbed up a little hill, through woods, to a vast desolate area. There was a huge mound of earth with a tractor on top, a big shallow pond below, a field of reeds, huge chunks of stone, and a few piles of broken painted wood. When we got to the top of the big mound and looked around — we could see the horizon in all directions and the boston skyline in the distance — I told her it was extremely unlikely that this was not where the hospital used to be. We sat down in long wavy grass under the bright sun in tshirts, drank maple soda, drew pictures, listened to cars go by in the distance over and over.

When I got home I looked up the old mental hospital campus and found that it is now fancy apartment buildings. I have no idea where Maeve and I were yesterday.
