Unless there are restrictions in place, you can camp almost anywhere on BLM and National Forest lands and immediately adjacent to most marked roads in the National Grasslands. You may not camp on any state land in Wyoming, but most is open to hunting.
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.
