Boise, ID ~
This is a popular place to exercise. Located behind the penitentiary are large bluffs and walking trails. Many people park their cars at the base of the hills and walk/jog the trails. You could spend all day here depending on how far you’d like to go. Many of these pictures were taken at the top of these bluffs.
As a side note, the penitentiary is said to be haunted. For those of you who are fans, the Ghost Adventures crew did an investigation here. Public tours are given if you’d like to try your hand at ghost hunting.
