Every man, boy and his dog is getting one for Christmas- wonder how long it will be before something happens and tehy will become much more regulated. + invasion of privacy too.
We have a fabulous nature reserve near here, with some fabulous wildlife, ibex, peregrines, chamois, marmots, and very rare rock swifts and even rarer tichodrom wallcreepers (the most wonderful mix of bright light grey and the brightest pink), and more. A limestone cliff a little bit like Malham Cove, but much bigger. Wildlife photographers have found nothing better than to use drones to take pictures of the nesting birds, and frightened them away- so no chicks raised ths year. Will they ever come back. Grrrrr.
Google Le Creux-du-Van, Neuchâtel, if you want to see the site.
