140 was really close to the field being that the foul ball area is practically non existent at wrigley field. The best is when the right fielders chase down balls right next to your seats and the out of play walls aren't that high up.
This place resembles Fenway Park in Boston for those of you that have been there, I could be wrong but I think they were built by the same company. The Green Monster in Boston was added to keep fans from being able to see into the ballpark without paying.

Like Fenway, Wrigley has it's share of support beams that will stand in your line of sight and become an obstruction but you don't have to worry about any of that in section 140 since it's a 'field box'. Picking seats shouldn't be that complicated but as much as they ask fans to spend at these games, it's worth the time and effort.
