Comfy and safer

I seldom have free time to play with my kid. And this is the thing that he is asking me all the time that he wants to have a swing set. He says, if I will not give him even a small one, he wants me to bring him to the nearby park even just once or twice a week. So, I am thinking that swing set is much comfy for him because it is a bit safer to just play at the yard rather than walking ten minutes or more in order for me to bring him to just enjoy playing at the park. With this, I am doing my best to save a lot for this. I am hopeful that I can give a swing set to him on or before his birthday.
