I've had some good experiences with it....I had an old log that was about to fall apart laying over a lil ways from a stand, so I saturated it with moleasses a few weeks ahead of time to let the deer get used to it and start using it.....by the time season rolled around the log was just about gone, just chunks of wood.....they tore right through it.

I've always found that, around here at least, the deer need a little time to get used to a new food source before they'll start using it....I've seen a lot of guys dump out corn the day before season and then hunt over it the next day, never see a thing. Most of my corn feeders and mineral pits stay out year round....I just turn the feed rate way down on the feeders during the summer.
