Interrupted only briefly by Valentine's gift-exchanges, the morning was filled with discussions about head trauma in an urban and wilderness setting. Andrea took over in the afternoon to review navigation concepts from yesterday, then oversee students putting together their own orienteering courses for fellow group members to follow. As we write, students are trekking through the forest using their new GPS skills and burgeoning situational awareness to develop a map of the local trail system down to the Rio Chires. For anyone accustomed to using UTMs, it's eye opening to work off of Costa Rican maps that use their own kilometer grid system which is wholly separate from ours. It takes time and practice to work between these maps and GPS receivers and be able to come up with a system that is useful and practical in an emergency.
Tomorrow, after sharing their hand-drawn maps, students will have a written exam and more instruction in spinal cord injury and bleeding and shock.
