In great deeds, something abides. On great fields, something stays. Forms change and pass; bodies disappear; but spirits linger, to consecrate ground for the vision-place of souls
generations that know us not and that we know not of, heart-drawn to see where and by whom great things were suffered and done for them, shall come to this deathless field, to ponder and dream; and lo! the shadow of a mighty presence shall wrap them in its bosom, and the power of the vision pass into their souls. .....Joshua Lawrence Chamberlain
My wife and I had exactly the same feeling when we visited....
Same here, and I've been there a lot (dozens of times). Walking out of the woods towards Emmitsburg Road (Pickett's charge), Wheatfield/Devil's Den area, and the unfinished railroad cut are especially noteworthy in this regard.
Devil’s Den in the bright daylight was eerie.
I’d hate to experience it after dusk...
