We had our first trip where we had to actually stop and use a DC charger. It was -10c and -15c when we stopped and pretty much all we did was run and grab a coffee before huddling back in the car. If it was a reasonable temperature we would have gone for a walk, and in hindsight we should have brought some books. We also like card/board games and are wondering if anyone has any recommendation for 2 player games that are easily played in the front seat? Or are there any other less obvious activities that you have found that take 30-40 min?
