I have been to the Grand Canyon four times. The first two times in the mid 1960's when I was only 5 or 6 years old. Some of my earliest identifiable memories are visiting the Grand Canyon, it leaves and impression on you. I remember looking over the edge, holding tight to my parents, the Bright Angle Lodge, eating the dining room (I have been told NASA Astronauts where in the dinning room, they were studying geology in anticipation of going to the moon.)
I have been back twice as an adult, in the mid 1980's and again in 2010. I only have a handful of images from the last visit, the one's taken with my phone. I had a few hundred digital images - lost in a hard drive failure - with the most recent backup about 8 months out of date.
