Thanks for the reply. I don't mind her on the property, just not on the porch where we found her. 

I let her go in the back yard by some thick foliage.

They do well just about everywhere, but if you don't want her on your property, your nearest patch of woods, especially near a source of water, would suit her just fine.

She's now even further away from one than before.

This little guy scared my mother something fierce while spring cleaning (we live in Westchester, NY). Pretty sure it's a Garter Snake. Is there anywhere in particular I should let him loose?
