I have had this experience in many places, but one of the strongest has been in Valley Forge. When I stand on the hills and feel the breeze, I feel like I'm standing on sacred ground. George Washington Chapel in VF Park is an amazing place of beauty and solitude. I was drawn there to pray on the day the plane went down in the Hudson River last winter - just before the accident. I heard about it on the radio as I drove home. Gave me shivers.
...you should try Jerusalem some time.
Another place that stands out is Gettysburg. Again, with my parents, we visited the museum (the one that rotates around you). First of all, the canons firing and the gun shots, yelling and noise are played at the volume you would have heard during the battle. Then you hear the screams and imagine the death and dying. Then you leave and walk the battleground and just about water it with your tears. Our lives have been so blessed and others have given so much. My heart and my soul are laid bare by those visits taken on lazy, hazy days of summer with the two people I adored most in life. Good parents, good friends, good mentors and no truer examples of what parents should be. I think I’d have happily gone with them to watch paint dry, but they chose things that would build my character, instead.
