You may want to call your law enforcement ahead of time to let them know what you plan on doing. If it was my law enforcement they probably would be off for the weekend! LOL
I once called in boating violation on a Friday evening to our Conservation Law Enforcement. (In our state you have to call the Sherriff's department first and they relay the information) Anyway, I was told there would not be an officer on duty until the following Monday. What a joke.
