Might be worth taking a look a at the Tecomate web site or search for 'food plot seed'. I use to sell a little Tecomate seed at deer shows. They have a good brochure that describes zones and times for planting various seeds. This way you aren't wasting time, fuel and money.
You could also go to a local feed/farm store and put together your own mix without the fancy bag. Just consider heeding the pro's suggestions at planting times, depths, soil prep.
My buddy (who I used to sell this stuff for) lives a mile down the road - his cameras are full of deer pictures because of his food plots. I didn't get any in this year and I can't find a deer! He is drawing all the does and bucks away from my place, I'm certain. Go for it! You'll be glad you did.
