Wanna Do Sports In The Winter? Well, here's an idea!

(Take the car out of your garage and park it reasonably close.)

For Tennis: 

Get your racket and start hitting it at the wall. For more fun, play with someone else and play a game where you hit it once at the wall, and then the other player hits it at the wall. Keep repeating.

Try to see how many you can get without it rolling back to you!

Here is a video of me trying the single player tennis:

For Basketball:

Have chalk and a hoop? If so, I think you're good to go!

First, put your hoop on the far back of your garage. Then, make some pointer lines. (I am not a basketball expert so I am not sure if that's what you call them, but what I mean is 1 pointer line, 3 pointer line) Next, put on a jersey and a couple of sweatbands, and I say you look like you're playing in the NBA!

For Swimming:

You want a crazy idea, well here it goes!

Fill up your inflatable pool and then... swim of course!

Your parents may not enjoy that and it will still be pretty cold put if you want a crazy (and fun!) summer I say give it a go!

(If you want to see how it worked out with me, I'll post a picture and video:))
