Maya,
I probably have about 1000-1200 3-4 prongers and the rest are 1 and 2 year olds. I had to do so much replanting from the drought damage in 2007 that most of my plants are new.

Google \"Drought monitor.\" That pretty much tells the story that a lot if us are in. Should be good for those outside of the severe + areas, if you are growing seed, digging roots or just enjoying the moisture!
