I guess you could say I hunt on the fly also. I check theold roads in the woods an fields, powerlines,creeks an etc.I look for a concentrated area of tracks or fresh rubs or scraps that lead tomy main stand areas I have located. When I find good sign that is alot of time where I will hunt. I have learned that when you do find hot sign hunt it ASAP, because the next day theymaybe somewhere else.
