The mutt has been making some noises when I take her for rides in her chariot, and mostly it is just her way of saying "hey stop, I wanted to sniff/poop/pee on that thing over there". However I found myself looking back quite a bit to check on her. The problem with that is, on a bike, where the head is pointing is often where the rest of the rider and bike end up going, and that is not great if I need to keep in a lane. Rear view mirrors are great, but they will not work well for keeping tabs on the mutt in her cart. So I found another solution, a rear view camera.
