Near Morgan Hill, along Hwy 152 in California.
You probably have to time this just right to get the best green grass. I was there during the 3rd week of March, but I think the grass gets even greener later in the Spring.
Along Hwy 152 in CA, there are countless green hills with twisty trees. I just happened upon Henry W. Coe State Park when I was looking for a place to stop. I had very little time, so I just stayed near the parking lot for this picture. I can't wait to make it back there some day to see the rest of the huge park!
