I lean toward “efficient entertainment”, but I do sometimes wonder what that chunk of my free time would look like otherwise.
A place to sit and watch for deer when hunting them. Often an elevated seat, either on it’s own frame or attached to a directly to a tree. It gives the hunter a better vantage point to see the surroundings from. It’s amazing just how few critters actually look up. I have seen many wild animals going about their daily business from one. From little birds landing around me to rabbits, raccoons, fox, the odd bear. And ever so often I see a deer. Sometimes I have shot, sometimes I have let them pass freely.
But I find it an excellent place to look inward into myself. It’s a far better place to see deeper and more honestly than any room in any building.
