Narrative: This field trip was a workout. The hike was long and mostly uphill. I was overdressed due to the fact that field trip 2 was so cold. I ended up shedding all my layers and having to carry many jackets the whole hike. I also made a silly mistake and grabbed poison oak. Luckily I did not have a reaction, however I am now scared to touch plants. I am still highly motivated by candy but need to refine my ID skills.
