I have read a few of Charlies books and followed his study closely over the years. Although im not entirely convinced of his theory, I am intrigued by his findings. One thing that i have learned from him is record keeping. I use a weekly planner to keep a daily journal throughout the hunting season and try to include as much relevant info as possible.
for example... "cut" stand- weds Nov 11 high 41 degrees- low 33 degrees -west wind 5-8 mph- clear skies- frosty- primary scrape on apple tree- worked heavily- new rub on tree to the west- 1 doe & 1 button buck from west @730- 1.5yo 8pt @ 8 on field edge- etc
Compiling this info over numerous years (along with trail cam info) has helped me develop patterns and has helped with picking the right location to hunt at a certain time with the evidence of why. Alot like fishing, recreating that magical day can be as simple as matching time of year and ideal conditions.
