Deer camp was my introduction to peach schnapps, and Budweiser beer. To this day, I can't stand either one. There was no water, pop, milk, juice, NOTHING else in camp to drink. i was young, and very well practiced with my new compound, and I KNEW I could consistently put 3 out of 4 arrows in a dixie cup at 20yards all day long. I had 2 beers and felt no different, but I could no longer put any two arrows within 6" of each other. I drank nothing but stream water after that, and I have never gone to deer camp without my own supplies since. (That was the only time like that, others complained as well)
We did make a trip into town for other supplies the next day.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
