Most law enforcement will tell you that without a complaint from the property owner, there will be no trouble. It isn't the cops you have to hide from, it's the power company that owns the lines. This makes it virtually impossible to get in trouble for riding powerline trails as it is very rare to find an actual representative of the company on the trail. Anyone that is out there is either a contractor or just like you and having fun.
Free advice is worth what you pay for it.
