Plus you have to consider the area. For instance, where I hunt over in Schliecher Co. TX (West Texas) is a totally different ecosystem even from where Droptine here is, let alone LA. So you have to see what works in your area. You might try asking local farmers what the deer are eating, (believe me they'll know they might even invite you to thin the herd a little ;) ) or even so far as to see what deer management companies in your area are using. Remember food plots arent just about attracting deer to kill, but for growing healthy ones that you can hunt in future seasons.
"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
-John Stewart Mill
