brr...! Here in Guatemala (at least where I'm at), the temperature during the day keeps between a comfortable 60 to 80 degrees; however at night, it can dip down into the 50s and maybe lower, although the boys aren't acquainted with snow.
Here in Guatemala, while they have glass windows in many places, the windows are not typically sealed/caulked/whatever allowing cockroaches, spiders, and the cold to come in around the edge. (A rough hole size is cut out of the cement blocks--at least it's cement here at the Hogar--with a saw or a machete, and the window is placed into that space and screwed to stay.)
So, here in Guatemala, I tend to be cold at night. Tonight I'm trying out a new sleeping configuration using BOTH of the fleece blankets I brought. That said, I will wish you all sweet dreams as I bury myself (and my frozen fingers and toes) under a sheet, two fleece blankets (admittedly, one is wrapped around only my feet), a quilt, and a Mayan blanket.
