In a large pot over medium-high heat add the bacon and cook until slightly crisp and no longer pink. Remove it to a plate with a slotted spoon.
Add the onion, celery, and garlic and cook until tender. Add the flour and stir.
Add in the juice from the clams, chicken broth, milk, and half and half, then stir until there aren't any clumps. Add in the potatoes.
Bring the pot to a boil and reduce heat to a simmer until the potatoes are tender and the soup is thick. Stir in the clams and salt and pepper to taste. Top with crumbled bacon and serve.
