RE: When to move the stand?
sooner....get rid of all that scent cover. That may be your trouble. After a rain human scent will be gone.
I never use any attracant scent and oder control is the best defence.
I want nothing but whats normal to the deer and that means I want the deer to smell nothing I bring in the woods. Use your knowledge of deer and let that be your primary tactic.
I see deer almost everyday using this philsophy.
