Yeah I would go with Salt right now as they are attracted to it during antler growth. Also I set my cams high as I can and then aim them down if possible for two reasons. One the sun can be an issue and two those curious critters like to nose them around and move them. Also look for obvious limbs hanging around that blow easily in the wind and cut them down or you will fill up your SD card on one windy day.
Just my two cents.
