Yes, we carry it with us everywhere we go.  We got a hard eyeglass case to keep it in along with the syringes, needles, how to instructions, band aid and alcohol prep pad.  We also carry extra cortef, thermometer and advil with us.  You never know...  Being prepared has allowed me to not worry so much about the what ifs.... (We live in the Eastern Sierra and in winter roads can close, accidents etc.)  Also, never leave the meds in a car to overheat or freeze.  Julia
