Have any plans for the weekend , Tom ?   Yeah , I ’ m going for a hike in the southern Rocky Mountains .   Oh , do you go hiking often ?   I go as much as I can . I love hiking because you can really get in touch with nature .   It would be nice to get out of the city . Do you want some company ?   Sure . But , it will be a long hike , 30 miles in three days . Have you been hiking before ?
