You should keep all of your clothes in an airtight container until you get out of your vehicle and are ready to hunt. It certainly helps reduce coffee, tobacco and food oders on your clothes.
If you have a great trail and you are not seeing deer you might use a trail timer on the trail to see when it is being used. It might be that it is a night trail and not used when you are there. Some trails are seasonal too. If a favorite food source ripens they may switch trails until the source is gone.
Remember deer have four things on their minds: Sex, food, security and escape. That is why if it were legal for deer to drink the best place to find them would be a bar!
