Probably one of the best hunting tips.. Take a break when calling and stop in to a Wawa, Sheetz, Rutters, for a cup of coffee and a Whoopie Pie..Caffeine peps you up.. Some callers will even use those caffeine shots you can buy at the register....if your going to hunt past 2:00 AM give you body a little caffeine.. why I guess you could even drink a a regular coke if you want too...
