Larry,
I have been on the boys field and yes it is hard as hell. I would compare it to placing marine grade carpet (The cheap stuff) on top of concrete. Seriously it felt like falling on slightly padded concrete.
More and more teams that use turf are going to the new (good) stuff like in the Ravens stadium. The field that my team uses for our home games (North Point) has that same new age turf.
In 2009 when the Cowboys are in the new mega stadium, I am sure this will be a problem of the past, as you know they will have the new stuff. Along with every bell and whistle that Jerry Jones has promised.
