soy beans
I think the soy beans will be fine for the first part of the season anyway. While you are looking on the trails that the deer are coming in on look for a mature white or red oak tree. The acorns will be falling and if you can find a nice oak in heavy cover near the trail that the deer are using you should be golden! Do what you can to set things up today! Deer notice a lot of human activity towards the beginning of the season and get spooky quickly. Act like you are the farmer while scouting, make noise, sing, smoke a cigar, the deer will know you're coming and move off for a while and return shortly. If you sneak around and spook them from a short distance they will recognize you as a predator. If you see a deer or jump one, only give it a quick glance. Don't duck and hide...remember the deer should think that you are just a farmer there to get some work done.
The sooner you do this the better. Find your tree, clear shooting lanes, and get out! If you go back on the first day and find things have changed then you can adjust as the season goes on.
When I was a kid I was so into seeing deer that I would set up stands in August and September and sit in them to see if deer were coming through. That is just plain dumb. Get in, get out, and go back when you can shoot them.
