Swing drills to do In a back yard without hitting a ball?

So sometimes I don't feel like going to the driving range after a day of work on the course but I still want to work on my swing for a little bit.  What kind of drills do you guys know that I could use and practice with in my back yard by taking full swings?

If it matters the main thing I want to improve on is my out of control slice that has developed this year.

So what are we talking here?  Like a 30 yard pitch?  I have about a half acre lot to work with.

A good tempo drill is hitting plastic wiffle golf balls in your back yard. They don't go very far, but you have to hit them squarely to get a good trajectory. Fat shots tend to pop up, and thin shots scoot about 6 feet before the grass grabs them.

One benefit for me: I don't try to kill the ball, and it helps me smooth out my tempo. (Fear not, with an actual golf ball at my feet, the extra foot-pounds of pressure jump back into my swing).

This is a great question because like yourself, I have the same problems - both with a slice (at times), and with limited space at home. The replies I've read were solid too. I've incorporated several of them lately. I love the mirror, and it's not because I like to look at myself. It shows me the difference between feel and reality. If you, or anyone else, come across anything else, please share.

With that much room, why not put up a hitting net..? I have one in my yard, and it's Small, very small. That way you can hit balls if you want.

I wouldn't be opposed to getting a net for my yard, but I wouldn't stop hitting the plastic balls. I like hitting those because it gives me an actual sight of ball flight.

Agreed. I use to hit em. The problem is, you don't get a feel for good contact, which is my only goal outside of my proper swing. You can hit a wiffle ball fat, or flip[ at it, and you may not tell what you did wrong. get a net, and a decent mat, and your set..
