Hmmmmm...fondest memory. Wow, that is a good question.
Hard to pin point, but I would have to say our family trips to Pine Top, Arizona. My Mom at the time had a boss that owned a cabin up there. Great area, lots to explore. What I loved about the cabin itself was that it had a loft on the top floor. I was an only child, so I had it all to myself. There were comic books up there, toys, and a small window that looked out over the trees. Even at a young age ( was probably around 9, or 10), I enjoyed my peaceful reflection time.
