But yes, bring the Phantom, there are some great views in Scotland, Wales, England, Ireland..... lots to see and film. So far, the CAA have taken a light touch to drones... the idiot press and knee jerk politicians will change that eventually, but for now, it's all good!
also, despite what some people say (i'm looking at you, brexiters), we have tons of open space, mountains (small ones, but nicely formed), rivers, streams, rain, fog...
