Last week I was in California to visit my parents. On Monday I took a hike with my dad. It was one of his pre-planned hikes that he organized for his church's hiking group. This one consisted of a bunch of photographs of the trail that guided your way along the paths. In order to follow the route you had to examine the photographs for visual clues. Even though he was with me, my dad gave me no clues. I was able to navigate us along the correct path, even though the original photos were taken 2 years previous.
Here's a video. Shot it with my Nikon still camera on movie mode. I love this camera's portability. Music by Howlin' Wolf.
