Acrostic: Glimpse of Pine Ridge

Lazy days fishing, or lost in a mine;Undertaking new ventures in business or the town; Marriage advice done by a bachelor? Fine. 
According to the almanac, grandpaP knows all the people around. 

Business partners for life, til they get out the rope; 

Nobody could be more faithful to another; 

Egotistical at times, could be their slippery slope; 

Remember Mousey Gray? To him they’re like his mother.
