Thankfully, the only ghosts I encountered on my trip to Casper, Wyoming were the ghosts of my childhood memories. Having spent the first half of my life in the Rocky Mountain range, there were many memories made. The thing about going back to a childhood haunt, however, is that you feel like you are living in the past and everyone just suddenly got older. How did that happen? Time. Time is tricky on ones view of the present, like a ghost playing with ones memories.
