What do you include in your field trip bags? Right now, I only have bare-bones supplies that comply with our staff first aid policy (i.e. what a general staff person is allowed to do) - a couple pairs of gloves, alcohol swabs and single-use saniwipes (not sure why, but WTH), some sterile gauze, and bandaids plus student-specific epi-pens... would you/do you include anything else?
