I tend to put her in the same bucket as the person (there’s one most years it seems) that lets their dog off the lead as the race approaches. There’s going to be one in any crowd as big as the tour attracts, and I’m not sure the potential of being sued will put them off - because they’re not the sort of people to think that far ahead. However, I might shrug a bit less if it was my face hitting a generously sized sheet of cardboard at fast km/h.
In any case, having caught up with the highlights, I enjoyed the stages so far.
