I would trade all of the early season Blacktail days, for a single day of late buck. Late season is the ticket.
Trailcams can be a good tool, but they don't give as much as an advantage as you would think. As far as trailcams go, here is what I get out of them:
1. Encouragement for the days I don't see a single deer -- When I start to question if Blacktails have become extinct.
2. They tell me the times that the deer are moving.
Blacktail are nocturnal by nature. Being persistent and hunting every morning/evening is the single most important thing you can do.
