Don't know when the bean harvest starts in your area but a good tactic for beans or corn is evening hunts. Lots of guys spook bucks they never knew where there heading to feed fields on opening morning. Bachlor groups will bed down and feed through the night getting one last fill up before first light. If you must hunt the am I wouldn't get within 500 yards of the feed field and hunt a funnel heading back to (buck) bedding areas.
