Well I live in South Eastern NH and there's a lot to do around here. You can hike Mt. Washington or any other sick mountains. There's a ton of cliff jumping spots. You can go to Boston or Manchester and chill out go around the city. You can hit up the beach Hampton, Rye, etc. Fishing is plentiful. Cow tipping works if you're in central NH. You can buy fireworks and set those off.
There's a ton of shit to do if you are near the seacoast.
