5. Make The Starlight Drive-In Settlement Radiation-Free
Here's a small-but-useful tip for the sizeable Starlight Drive area, as the game doesn't flag up that there's a way to remove radiation from any area, let alone one where you'll be bringing a swarm of followers. Firstly, you want to head over to the radioactive barrels that are contributing to your increasingly high Rads meter, and remove them whilst in the Construction menu. Second, is to build a fence around the pool of waste in the centre, as your many followers won't think twice about pulling an Adam West and wading on in. You should get a sizeable chunk of experience from doing this, and you can add a Purifier to make sure the water left stays clean.
