i think you answered your own question. deer will, usually, bed in thick patches of timber, brush, woods, etc...if you are hunting out west typically following the 7/8's rule and you can find them bedded next to trees, rocks, brush, etc.

the term "too thick" cannot be used when describing deer bedding areas...the thicker the bedder (usually)...not always and it really depends on the area you hunt.....if it is more open with small patches of thick stuff then they may be in the thick stuff...if not then they will be in an area with wind at their backs and a good view in front of them. try putting yourself in their shoes..if you were being hunted....where would you be bedded down at?

deer, IMO, will not and do not always bed in the same spot day in and day out
