The Steelers still haven't decided what to do about the now infamous grass at Heinz Field. The team now is removing the turf portion that was installed over the old field in November, but not because they are going to put in an artificial surface.
The original surface is a mix of grass and some artificial fibers, according to the Pittsburgh Post-Gazette.
My position remains the same -- put in the field turf, especially if you plan to keep using the stadium for high school and University of Pittsburgh games along with Steelers contests. The players may say natural grass doesn't bother their joints as much, but they'll thank you during a monsoon or snowstorm in November, December or January, especially when their feet aren't sinking in the muck.
Update: In case you're curious, here is a link to my original post on the issue. It was on Lake Affected.
