Here is my code:

```
if (state == 'AZ' || state == 'CO' || state == 'DC' || state == 'IA' || state == 'LA' || state == 'MN' || state == 'NC' || state == 'ND' || state == 'NM' || state == 'NV' || state == 'OR' || state == 'SC' || state == 'TN' || state == 'VA' || state == 'WA' || state == 'WI' || state == 'WY') {}

```

Is there an easier way to write this using an array? This works, but I want it to be cleaner!
