Bowling is a great activity for the summer. It's indoors, which means air conditioning; it's something you can do with friends and family; and it's fun! Go bowling with your family and friends!
Imagine a hot day (it can get really hot in the summer). You can't stay outside for five minutes without sweating. Your parents want to get out of the house to do something, but it's just TOO hot! But, with bowling, you can bring the fun indoors!
Also, bowling isn't fun with just one! This is an opportunity to have some fun with others! A little friendly competition can't hurt! ;) Afterwards, you can always get a yummy treat. May I suggest ice cream?
Bowling is a great activity to do this summer. I have done it a few times myself. Go bowling!
