RE: How many of you can last all day....
I've done it and it isn't that bad at all. Most of all you need a comfortable stand like a Summit. If you have a time when there is not a lot of activity going on, a book or magazine is a good thing to have. I only bring a bottle of water and a couple of candy bars to hold me over till I get home again. It is a lot of fun if you are able to do it, but you have to put your mind to it though and stick with your plan. I've seen some of the best deer ever during the off peak times of day, rut or not. Good luck
