Between Nashville, Tn and Franklin, Ky on I-65 N and S, police hide in tree blinds and behind hills in the median. I think the speed limits are fine(70mph) my problem with this area is that the police hide in the trees and bushes. This causes a reaction of sudden surprise by motorists and people will lock down their brakes even when they are going the speed limit. I have seen several accidents as a direct result of these tactics and the reaction that they cause. If the police were really interested in slowing traffic down, I would think that they would want to be more visible. This tactic makes one feel that the only reason that they are out there is to generate revenue.
