This is great news. There was absolutely no way the turf currently installed was going to get through next year alone with three teams playing there.
For those who are curious, the new surface is going to be FieldTurf's latest, the Revolution Turf. It's so new I can't find anything about it other than a press release. It's not grass, but this is a good solution at least for a few seasons.
