Kate and Sarah, known the world round as Pinchette #1 and Pinchette #2. Facebook told me this photo was from 8 years ago which sounds about right. Sarah (r) was headed off to a school dance (in her senior year at HS) and I nabbed this shot of the two of them.
Nowadays, Sarah is in the Fairfax County, VA Police Academy working on being a cop and Kate is on the edge of 30, a solid employee with a contracting company near Ft Belvoir making sure defense threat reduction folks can travel around the world without problems.
So very proud of these two. Very proud.

Great picture. I bet your mom loves them.
