using sents is very effective.However it must be the right time. My friend put some tinks out a couple weeks ago @ begining of rifle season and it wasn' t the rut yet. he saw a huge 10 pointer across a field and grunted, the old boy came in but when he got to the sent cans it freaked out! I mean freaked out .When I know when the peak of the rut is and where some active primary scapes are located, then I will make a sent trail w/ wool pads on my boots going thru scrapes and crossing trails or runs, then I will walk up wind of my stand and leave them about 4 ft. of the ground.....Had bucks walk right in my tracks w/ love in their hearts and tongues hangin" out......obliterous to what was about to happen....ps...." James Valley" was the best sent I ever used......
