Since Valentine's is coming up I give you how the main six eventually all got married

Note, originally it was hella not legal for them to marry, which is why they traveled around to different states to marry because 'well it's legal in Washington!'. Gov did some shady business and it's all legal. 

That being said, here it is (focused on how they married DC): 

-Florida watched Escape from Tomorrow once and wanted to get married at Disneyworld without anyone knowing. He wore his favorite tank top and his flamingo bowtie for the occasion. They married on Splash Mountain and were soaked by the time they said 'I Do'. 

-Louisiana and DC got married on Bourbon street. It was kind of a proper wedding ceremony and a party. Loui refused to lose his Tigers jersey or beads, but he did put on a Midas Gras tie for the occasion. Not many remember that wedding ceremony. 

-Texas insisted on a church wedding back in Texas, which he got. It was an actual proper wedding ceremony though Texas didn't take off his cowboy hat. When DC and Texas kissed to seal the deal, Texas in celebration shot up in the air with his gun, there's a hole in the roof now.

-New York and DC were supposed to have a proper wedding ceremony really they were. But Mass and Cut stressed York out with the planning so much he panicked. So DC and York snuck off ten minutes before the ceremony and got married at the courthouse. 

-California scoffed at the idea of a wedding ceremony and wanted to get married at a courthouse until York stole his idea. Luckily Washington told California about handfasting ceremonies and it intrigued both of them so much that they chose that. California and DC also got the honor of being married on the date of the first meeting. 

I haven't decided how Wyoming and DC get married. Knowing Wyoming it'd be something small.
