[FRIAM] "Weather line" on 14

Sun Jun 23 12:09:58 EDT 2024

And Kim Sorvig lives under the weather line off 14.

btw, when I was searching Wed night on Galisteo Dike and Creston, Kim's
name came up in the Thornton Ranch Open Space Master Plan in the list of
biology/natural resources  acknowledgements.
