Well, actually I meant a rattle snake, I do know that there are alot of harmless snakes that are actually good for keeping venomous snakes away. I will admit the harmless ones give me the creeps, but I am not afraid of them. And would not kill one, though I may hope it makes its way out of my presance quickly. As for a rattler, I am sorry to offend anyone, but I have three curious kids and it terifies that they might stumble upon one in the back yard, and so I do believe that if I find one back there, it will need to be dealt with quickly, no time to wait for someone who can relocate it to be found and arrive.
As for the fact that they are all over the valley, I know that but since my house backs up to the wash between hwy 2 and LPC, I was wondering if there could be one just ouside my back door so I could be aware of it.
