It’s because CA is full of aliens of all types - legal, illegal, Democrats, liberals, socialists. So seeing a UFO is not that big of a deal to them. It’s kind of like normal people seeing houses, people, cars, trees. But to them, it’s UFOs.

Amazing, someone from Washington throwing stones at California, people in glass houses and all that.

The reason California reports more sightings is because Area 51 pilots like to test the experimental craft over us.

It’s the most populous state
It’s also has a very large area
Large expanses with little or no light pollution
Moderate climate (for the most part) makes stargazing a decent hobby

Based solely on population the #1 outlier is Montana (47 sightings, #34 of 50 states)
To me a bigger outlier is Connecticut (146 sightings - #9 out of 50 states, also has a very small area, cold climate, lots of light pollution).

At the other extreme is Texas (116 sightings - #12 out of 50 states). Based on population you would expect more.
