A thin place is said to be a location where there is but a veil between Heaven and earth, making them close enough to one another to touch. There are many thin places in the world where people can feel this. Being in Ireland last year confirmed this for me with the feeling of complete connection to all that is.
I took the picture on my home page while visiting my cousin on Cape Cod last September. The low pixel camera in my phone created a muted, old photo effect: I was there then, and then could have been a time now or one before. Thin, indeed.
