RE: Do you think Scent Lok is a must?
Definitely not a must but, take care with your field clothes. Contain them as scent free as possible, use some cover scent of something in your area, i.e. if you hunt the oaks use acorn spray, pines use pine scent etc. etc.Always try to hunt where the wind is not blowing into a bedding area, although this is not always easy or possible.
Good luck out there this season!
