Prayer Request

Hey,
This is my first post, and I have a prayer request.
My older brother, and some other people from church, are going on a Mission Trip in Costa Rico in a few weeks, for eight days. They will be staying in a really nice hotel, that is surrounded by a big wall, and armed guards (Ha ha, makes you feel safe, doesn't it?). They will be building a house for Missionaires (sp?). They will have one free day to do as they please.
I would like you to pray for their safety flying there, while their there, and flying back.
Thank you,
Sarah (or Zimri, call me what you wish)
