Karla, I love the pillowcases.
Don't worry about Rachel, she will be fine.
My youngest DD did similiar things when
she was in college: backpacking in Chilie
to count "endangered" deer; sailing a tall
ship to the Carribean from Wood's Hole
among other things and did just fine........
She is an adventurer and
always will be, we just accept it now...
(I didn't say I didn't (and don't) still
worry. That's what moms do best!)
