never infront of the brush or tree...always behind them..if you are hunting without any blind....

i find it best to be just back into the cover..put some limbs in front of you (small ones) from the or just stand or sit in the middle of some small trees with some cover around you...this will help in concelment and also would help in allowing you to move...

my best advice though would be to get a blind...weather big or small you can pick a single person blind up on ebay for like $50 or just a turkey style ground blind (half-blind with stakes) you can buy them for like $20...good luck
