I do it all the time! haha but not for a long period of time. Heck, with two kids under 5, you nap whenever you can! When things get that quiet, sometimes it's hard to stay awake.
Nahh, I usually take a quick nap when I get in my stand first thing in the morning before daylight (until about a half-hour before sunup)
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
