“My city is an urban area with more than four million people. Like many people here, I work in manufacturing. My brother is a commercial fisherman. We are surrounded by mountains, but also have many beautiful beaches. Our Mediterranean climate makes the weather generally mild. It rains occasionally. Sometimes we worry about chaparral fires in the nearby hills.”

If u’re asking where this place is, it’s Los Angeles near Pacific Ocean by coast ranges and the Sierra Nevada mount.

There can be more freedom for them

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
