We all know about the risks posed to cyclists by dogs, ninjas, ninja dogs, podestrians (sic), and Hybrid cars / ERV's in stealth mode. But I have to add a new one, as of last night. Drones, with Go Pro's strapped to them. Watch out folks, they'll be coming to a park / trail near you soon. They really have got the potential to be a proper pain in the arse. Well there will be one less to worry about, in my locale now anyway.
