139 was a decent section but well below par compared to the other seats that are available in this ballpark. You don't get to look at the Pittsburgh skyline during the game since your back will be to it. But the Riverwalk area is just behind these seats so you can get to it quickly if you want to take a break from the game to stretch your legs.
There is a concession nearby called 'North Shore Nacho Express' and the nachos were amazing.
If you've ever watched a Pirates game on tv and noticed the green shrubbery area in center field that has the word 'Pirates' carved into it, these seats are right next to it. Comfortable seats but just too far from the infield for me. I'll sit somewhere else at the next Pirates game I go to.
