In a large soup pot cook bacon slowly to render fat. When bacon is crisp and brown remove with a slotted spoon to paper towels to drain; set aside for garnish. In bacon fat sauté leeks for 3 minutes. Add potatoes, squash and pumpkin. Cook, stirring, 5 minutes. Add stock and bring to a boil; reduce heat and simmer 30 to 40 minutes or until vegetables are tender. Add cream and herbs. Season to taste with salt and pepper; add brown sugar if desired. To serve, spoon into hollowed out squash or warmed tureen and garnish with bacon.
