I am planning on doing that. I have a huge backyard with so much potential. I just need to learn about gardening...I have had this house since Aug of 07 so it is all new to me. Remmy, I grew up around cactuses..LOL!
It's fun, a lot of work, and the rewards are GREAT! Very educational too.
Secondly like I mentioned, one can lose weight, so far I have lost 20 pounds since my greenhouse was completed!

I suggest start off with a small garden to see how you would like it. Also plant your favorite fruit and vegetables that you know you would eat. It doesn't hurt to mix some vegetable plants next to a flowering plant due to insect control.
You can try a box garden, or if you really want to put a lot of sweat in to it--till your own land.
Good luck!
