ok..next year i will be on my own if i want to be and plan to bow hunt also...my dad doesnt use calls or scents or anything...i myself dont believe in scentlock stuff or anything like that....this year i bought a grunt call to stop them for good shots but not calling...i am willing to try some scents and maybe calls next year when im alone...so what are some good attracting scents...like name brand and kinda of scent and form ect... abd how long will it last? i may hunt from a stand this year and my dad will be a few hundred yards away so i can use it once this year...will it keep till next year even after its been open? thanx alot..
