We've had a lot of people come and look at our house in the past few weeks. When they come, it's best if we leave so they can roam freely. On one such occasion we went to South Park, up Provo Canyon. (I only just remembered that there's a cartoon of the same name. We are entirely unaffiliated with said cartoon.) While the girls and Nate were off looking for geocaches, I followed Charlie along the trails.
I don't think he even realized I was following him. He was delighted to just walk and walk and walk. We'll miss the mountains when we move--we don't spend enough time exploring them as it is.
