RE: Alternatives to tree steps.
To help conceal bolts use your cordless and drill holes in the base of some branches and slip them over the bolts.
If you have cut any branches off your stand tree or cut any limbs for shooting lanes rub the cut with dirt. Those fresh cuts really stand out and can give up your stand to other hunters.
If they really want the stand they will get it. Your best bet is always a climber or portable you bring in and take out.
