The only limit is your imagination. You don't have to go far, but as someone mentioned sunrise and sunset will give you the best lighting. I took this in my neighborhood. Even places you've been multiple times can still be interesting from varying perspectives. I've learned a lot about aerial photography since joining this forum.

This one was taken not far from home. Honestly, this was more of an accident as I went there mainly for video. I didn't know I had this little gem until I got home.

This one was taken on my way to Vegas. Stopped by on the side of the road. Like I said the only limit is your imagination. Happy flying!
