RE: what should i do now?
well, it is his land so there is that issue..... Also, and I mean this with all due respect, COVER SCENT IS OVER RATED. I've been in deer camp for days, smelling like a peach orchard boar and had deer walk within yards of me.
It may be that there is just not much game where your stand is. I seriously doubt that the lack of your buddy's cover scent has anything to do with you not seeing game. you might want to find another place to hunt.
