RE: "Destination" food source = LONG sits
For me, I'm hunting those beans early on. You can get yourself into a situation when there are deer in the field, and you need to leave though. I have waited many times until full dark, and snuck out. I know you use a climber, and so do I. In these cases, I don't re-assemble it, just carry it out as two pieces to avoid making any unnecessary noise, although with the Summit Skin, I can get my clomber together pretty darn quietly.
The deer will come out to that field, and they mill around alot, just have to be patient and hope they come by.
