@naruto100 Yes, my initial intention to go to park is not to save money, but it really does. It's really good to engage the kids to the nature, and it's good for us too. Moreover, there are many free "toys" in the nature, they are really good for kids and save us lots of money too. My kids enjoy picnic at the park too, we just bring some simple food, and they enjoy playing and eating at the park. The kids have lots of fun and we have precious time staying together as well. The kids are healthier playing in the nature as well.
