You guys don't know BAD! Every time I have gone out so far I have picked off at least 100. SOme spots are worse than others and we could have 40-50 in a 100yd walk. We pick them off as we go. But somehow I get home and find another dozen or so in my clothes............and for the next couple of days I find them onb me b/c they escape and get on me in my car. The bear I killed was infested....... I mean to the point of gross!
