PREDATE

Starting your baitpile early could give you time to study deer tracks.
Is there a reason you chose to put your stand in that spot? If you know that deer are traveling through that area, then yes they might pop out anywhere, but remember, deer are still on a routine. Wake up, go eat, go lay down, repeat. If you can find out where they're eating and sleeping you then just need to connect the dots. Are there red oak(acorns) around? How about apples? Is there a thick area where they bed down?
I'm not using a trailcam this year either. You'll just need to walk around and look for deer sign. If you see tracks,wich way are they going?
The more you "study" deer's habits the more you'll be able to predict their movement patterns!
About your camo, if that's all you have, then by all means wear it. If you could get ahold of some regular camo, that would be better. More importantly, try not to move around in your stand. Only move your eyes. Do you practice scent control?
Good luck!
