At the weekend I was out in Fen Drayton in Cambridgeshire making use of some good weather to take some photos of the landscape and big skies. The area is easily reachable by taking the Guided Busway from Cambridge in the direction of St Ives. Only a handful of buses run along the route, but it also has a nice cycleway, used for commuting into Cambridge, taking social rides, and for general fitness (there are a lot of joggers on it too).
NB. I do consider issues surrounding flying a drone near a nature reserve – avoiding mating times, and for the most part staying very high to minimise my impact. (Indeed this site is close to an airfield that probably has considerably more impact on the wildlife). I also flew from public areas rather than the reserve itself. On the day I flew, I suspect that whoever was very nearby with their shotgun was the bigger issue.
