Be careful where you fly there. All State Parks are NFZ by state law, in addition to any National Parks. There are also many wildlife refuges that are also off limits.
Flying on and near beaches you have to be extra vigilant for helicopter traffic. They are used a lot for Coast Guard, law enforcement, and tourist charters. They can legally fly lower than fixed wing aircraft and they do a lot of it along the beaches.
Well being that the breeze is so small I never thought about that. I wouldn't be a problem because I rarely take it over 70 feet or so.
