If local authorities are hassling you about flying in what is clearly navigable US airspace, here is some potent information you can use to educate them.

(NOTE: State-level laws and regulations can only dictate where you may take off and land from, NOT what airspace in which you may fly.)

From the FAA:

UAS flying in a yard or over  private or business property is considered to be in navigable airspace.  Navigable airspace is from the ground up. Anyone flying a UAS in compliance with FAA rules is permitted to fly in all such navigable airspace.  The FAA regulates the airspace not local ordinates [It] is a federal offense to interfere with the operation of an aircraft, so private property owners and business owners are prohibited from interfering with or preventing the operations of a UAS in navigable airspace even if that space is private property.
