Region 13

Reno looks to be in the middle of region 13, so are we north or south?

Sorry but.... Wrong.

Yea I would be great if winter was like this, but it's January 18th and 51°f outside and we haven't had snow scince Christmas, and even then it wasn't much. Interesting prediction but incorrect, mabey next year.
