Since I am not working anymore I'll usually stay out for the season witch is 30 days for deer and elk not counting small game. Now I really don't get serrious over Labor Day with all the extra hunters in the field or if it is raining or snowing. But if it does snow I'm out there as soon as it quits. I'll also have to take a time out if I shoot one of the critters until I get it taken care of.
last year I put in about 30 days of archery in colorado. Now that I moved back to FL there are multiple archery season for different parts of the state. Hell I could hunt for almost 4 months traight with a bow if i wanted too.
It will probably be more like 2 months this year. I try to be in the woods every chance I get during open season.
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
