Man day 21 started off a bit stressful. We started driving towards our first stop, Kolugljúfur Canyon, when going over a pass the AdBlue light came on in the car. I remember last time I rented a camper the lady there was like if this light comes on you need to immediately get more AdBlue!! If you turn off the car you won't be able to turn it on again!! So we were in the middle of nowhere not close to any towns so Raymond was trying to figure out where we could get this and how far away it was. The only time I remembered seeing an AdBlue pump was in Reykyavik, which was kind of far away.
