Question: Thank you for that!  Can you filter that list to show only the customers living in Colorado?
SQL: SELECT t1.customer_name FROM customers AS t1 JOIN customer_addresses AS t2 ON t1.customer_id   =   t2.customer_id JOIN addresses AS t3 ON t2.address_id   =   t3.address_id WHERE t3.state_province_county   =   "Colorado"
