Think you're pulling a fast one by pouring a different kind of brew in your coffee cup? You're not fooling police on Rye Beach, as special enforcement steps up patrol this summer.

According to Seacoast Online, the board of selectmen in Rye approved a three year memorandum of agreement with the state of New Hampshire Parks and Recreation. Agreed on Monday, a major focus will be police enforcement on state beaches.

Rye Police Chief Kevin Walsh told Seacoast "We have adults that are hiding it and putting it in coffee mugs. We know what’s in there and we’re not allowed to look in, but here’s the bottom line: It’s our beaches and no one should be bringing alcohol to the beaches.” What the chief views as a "big problem" will be enforced with undercover patrols. "What happens with alcohol is fights, littering and other disrespectful conduct.”

With memorial Day Weekend approaching, the message has been reinforced; Alcohol is prohibited on state beaches regardless of age.
