Nice, good job! A couple unsolicited thoughts to think...
If you are going to e-fence your plot and one side of it lays right next to cover, which is what it looks like in the photos, I think you may have some fence "run-ins" and/or volunteer weeds that will short the fence on that side that you might have trouble keeping mowed/sprayed. My sense is that deer will burst from cover and hit your fence.
The one year I ran e-fence, it worked pretty well...until the rut started. Then, about every time I got around it I found one or two spots that had been hit and knocked over. I assume once the chasing phase started that there were then accidental run-ins due to that.
If I wanted a bean plot still there in late season, even if the e-fence works well, I would think about planting them later than April. It might work well, I am not sure, my thought is that you may want to plant in mid-June'ish to have them still standing well in January.
I assume you used RR or LibertyLink beans, so you can over spray them once they are up. My biggest challenge, short of the dreaded SE Iowa recurring summertime drought, is weed control. Long story short, I have really struggled with beans over the years and too many weeds/grasses has been one of the biggies that I have fought. Fight the weeds early and hard to keep your plot working for you.
Just some thoughts, good luck!
