Afternoon Fun in Bloomfield

It's a beautiful partly sunny day in Bloomfield with a high of 80 degrees, making it a perfect day to get outdoors with the kids or take the dog for a walk. Americano Creek, which flows along the south edge of our town, might be a great spot to explore, but I'm curious to know what other local spots are perfect for a free afternoon. What's your favorite place to take the kids or your dog on a day like today?
