In New Zealand, we have a fair few native animals running round. From Tuataras to Wetas (hence Weta Workshop - the Lord of the Rings folk), most of them get more active as the sun goes down. Over in Finland, that must be the case for the local reindeer population too, because in order to prevent the 4,000 deaths at the wheels of vehicles every year, herders are being tasked with spray-painting fur and antlers alike with reflective paint.
Now Finland shares a border with Norway, (aka the home of Thor, Odin, Loki, and Vikings), so they are not the kind of people you want to laugh at, but come on. Sure this may save a few regular folk from knocking Santa's little helpers for six across the bonnet, but how about the Star Wars fans who will drive into trees while watching lightsabers jousting on the roadside?
See that's what sucks about this world - as soon as you fix one problem you create another. Thor with lightning looking luminescent reindeer included.
What do you think?
