How can i remember the 13 colonies?

You can think of a sentence with each letter, like:

Very Many Nice Men Came Running Down North Street, Not Needing Police Guards.

But, its hard since theres Maryland AND Mass. So..you could remember a poem:

There's a cow named Georgia (Georgia)

IT's a Jersey cow (New Jersey)

She's sitting on top the Empire State Building ( New York)

Singing a couple of Christmas carols (n & s Carolina)

Under her arm is a Virginia Ham (Virginia and New Hamshire)

The cow is wearing yellow underwear (rhymes with Delaware)

In it's hoof is a pencil (Pennsylvania)

The cow is making a coonect-the-dots drawing (Connecticut)

of Marilyn Monroe (Maryland)

Walking down a road (Rhode Island)

Going to mass (Massachusetts)

It's pretty long, but that's all mainly, besides just memorizing it.
