Forbes Field is not located in the state of Colorado, but rather in Pittsburgh, Pennsylvania. It was a baseball stadium that hosted the Pittsburgh Pirates from 1909 to 1970.

As for reasons to visit Forbes Field, it no longer exists as it was demolished in 1972. However, some points of interest to see in Pittsburgh include the Carnegie Museum of Natural History, the Andy Warhol Museum, and the Duquesne Incline.

Interesting facts about Forbes Field include that it was the first stadium to have a wall painted in a bright color (green) to help outfielders see the ball better, and it was also the site of the longest game in World Series history in 1927.

The best time of year to visit Pittsburgh is typically in the summer months, from June to August, when the weather is warm and there are many outdoor events and activities.
