Those beans will tell you a lot over the summer. If you can keep out of it and glass from afar - you'll see what caliber of deer are living in the area.

Just don't expect to get much mileage out of hunting the beans... At least in my area, the beans are usually drying up and coming off right around the 10/1. But for all of August/September, I frequently perch my ass over the beanfields with the scope in my face.They'll come to it like flies on poo.

If your season comes in a little earlier than ours - you could really take advantage of that foodsource.
