Its easy for panic to set in when you get "turned around".
I was probably 14-15 and elk hunting over near Taneum Creek. There are roads everywhere,and its almost impossible to get truly lost. I was going to go on a short hike and be right back to the truck. I had walked about 5 yds into the woods and jumped a spike. I took off in hot pursuit,not paying a bit of attention to where I was going.
I'm not sure how long I chased that spike before I realized I had no clue where I was. Looked around and thought to myself "uh,oh"
I found my way out to a road and before too long a truck drove by. He was just about as lost as I was so he wasn't any help.

A few minutes later another truck drove by and he was able to tell me where I was. My short hike turned into a couple hours of stumbling around trying to figure out where the truck was.
Like I said,that first few minutes of realizing you don't know where you are,is not a good feeling.
