Both my brother-in-law and myself dip. Two seasons ago, we were hunting together and had been spitting on the ground (Vanilla Skoal). Two doe's came in right underneath my brother-in-law's stand and started licking the leaves. Just to further experiment, he spit on one of the doe's back. The other does must have smelled the Vanilla and began licking the spit right off of the doe's back. They never did figure it out and we still laugh about it. Since then I have installed a cup holder on my Summit Vipor for a bottle w/ lid. I have killed some nice bucks with a dip in and spitting on the ground, but I have started taking more scent elimination precautions including not spitting on the ground, just in case. Not dipping in the stand at all would probably be the best. You can get the same argument about people who smoke on the stand and pee out of the stand. There always seems to be someone who has killed giant bucks while doing any of the above. I guess it becomes personal preference as to how careful you want to be. A really smart, mature buck could probably tell something wasn't right long before you even saw him, unless conditions, such as wind, were not in his favor at the time.
