RE: All day sits...how do you do it?
All day sits can be tortureous. But as mentioned the above things can make them go by a little easier. The best thing that makes them go by is continual deer sightings.I pulled a couple last season in conditions that I question my sanity. No deer should be worth that amount of effort.
On a funny note texting on stand passes the time real well. And honestly a "Cheering" section on the other end, can convince you to stick it out when you aren't seeing anything.
