definitely get out there and do some scouting ASAP to see what the deer are/have been doing over the past few months. You can start scouting during the summer but you have to remember that dee will change their migratory patterns in the summer and they may be totally different from what you're seeing during hunting season. Like timbercruiser said the big bucks are going to stay where they feel safe. As for a 30x30 food plot, you might want to look into doing some mineral supplementation rather than making such a small food plot.
