greetings evan,
did use scents at one time. when slooow hunting thru the woods, tied a scented rag to my boots to leave a trail... while doing this, tied a small scented patch to a branch here and there.
later on would repeat the route. almost always got a shot. did get my first deer with a bow that way. he would not leave that scented patch for anything. so he got an arrow..
BTW, my bows don't have training wheels on them. :grin: :rotf: :blah:
back to your question, if done rite, there won't be any scent left at the end of the season. :wink:
good luck and ..ttfn..grampa..
