Water rights is the biggest issue in the West, and the world -- the Israel/Palestinian conflict is more about water rights than anything else. Land, yes, but more importantly about the water running under it.
I find it interesting comparing the SLC rain data I linked to above, and the perception of those who live there. I suppose even if SLC gets an inch of rain every month, when it is such low humidity it must evaporate right after hitting the ground and not soak in. So different from here!
