It's fun when relatives visit, but finding a place in the Mile High City that will please dear old Dad can sometimes be a tricky task. This nearly seventy-year-old transportation history museum near the Coliseum (the museum's original home is now the REI flagship store) is at your service. Dad will enjoy the old-timey cars at the Forney, and the look of childlike wonder on his face when he gets to climb into the Union Pacific Big Boy is well worth the $17 admission fee.
