To me this is very situational - ie. it's both PLACE, and TIME:
Ireland, just south of Killarney, on my families ancestorial land, Killeagh, in what is now a national park, on the highlands above the Ring of Kerry, looking down on the Mucross Estate where my Great Grandfather was the Head Gameskeeper for the Bonnie Vincent family, wind blowing in my face, staring at a large deer.
Jerusalem, with my family, hearing the Adhan and watching the Muslim Quarter shut down as they went to pray, and realizing those two square miles that have been fought over forever are all about one thing, FAITH.
Up above main camp at Crusader in the BaviaansRiver, first light, seeing the early rays of sun cast upon a WaterBuck, as he stood in full glory, I let him live, I had taken one of his brothers earlier in the week.
Watching my amazing wife of 33 years walk down the aisle, the church built in the early 1900's, one of my groomsmen's Grandfather had been a mason and installed the incredible array of Irish marble, knowing that my Grandparents were married in the same church.
Outside Ketchikan, Alaska, back transom of twenty-foot fishing boat, fighting to reel in my first Silver Salmon, as a bald eagle flew over.
In the hills Steinbeck so aptly described, North of Paso Robles, California, early light, early 1980's, having run up a hill, winded, borrowed Steyr SSG69 chambered in .308 in my hands, stupid young guide says if you pull the trigger, it's your shot, big Russian boar headed up the opposite hill, nearly four hundred yards out, steadied the rifle on my knee and pulled the two stage trigger, boar went down, my first big game animal was in the books.
Upper Owens River Valley, fly fishing pool to pool, catch and release, and losing all sense of time until my wife hiked to tell me it was time to go back to the cabin.
...and my list goes on and on and on.....
One memory, one place, one experience, does not define us, good or bad, as we probably all have both types in the library, they are just chapters in the book of our lives we write in each day.
