tonyj, it isn't clear what you need the grass texture for - is it just for you or are you going to try and sell it? If its just for your own non-commercial project perhaps you can use some of this map here, which is unfinished. I made this river as part of a larger battlemap commission that fell through but the grass part is pretty ok, though it might be the wrong colour for you. I could probably find the old file with the grass without the river; I recall I had made a dirt path too but I'm not sure where that will be now.
