I have a drone and live in the US. Federal laws are not as strict as other countries but states also make their own regulations as well and some of them take them to the extreme. I used to live in Vermont and they have almost no drone laws and no airports (you can even fly in state parks). I now live in Massachusetts and there’s a lot more airports, you’re not allowed to fly on Massachusetts department of conservation land and state parks, and a lot of towns don’t allow drones in their parks either. That leaves residential areas or areas that are close to people’s homes and then people get paranoid because there’s a drone nearby.
Also it’s difficult to know what the landscape will look like from the air. Sometimes it looks nice and sometimes it doesn’t.
You can make a half heart with your hand and have a photo of you two putting your hands together (not touching) to make a whole heart. Maybe use a stuffed heart and hold it together (cliche but it might look cute). If both of you have a common hobby or favorite character or tv show you can use a plushy or themed items. Maybe use a small tree and have one of you on each side, and hands on the center of the trunk at face level (so you get faces and the ring in the photo). If your shadows are allowed to touch I think you could create some interesting photos.
