I was training at a county park here in this Nazi state of NJ and ran in to the county security guards they told me that if the dog doesn't have a leash I had to leave. I informed them that the dog had a e-collar and they basically said tough. I was speaking to someone yesterday and they informed me that there may be case law to support my issue that a e-collar is the same a leash?? Any help would be appreciated I would go else where but it is a very good spot to train. Thanks Chris
