Hi @nicol1! I’m Amethyst from Southern West Virginia, welcome to the forum! 
I honestly am not sure if we have any Detroit witches, but you’ll make friends here from all over the world! I came here feeling really isolated and I’m not now!
In case you’re interested though, there’s a poll, Where in the World are the Witches that might help you find some people closer to you!
Like I said though, you’ll find people from everywhere here looking to make friends.
