I'm at it right now and have been for the past two weeks. Sitting on the back porch of my new house looking out over the land. Right now I'm inside waiting for the rain to roll in.
Cape Cod on the deck of the place that we rent finishing the book that I started on the beach, skin warm from a day in the sun, hair a disaster but smelling like coppertone and salt water.
My vegetable garden is my happy place lately. Standing out there watering it, with a cup of hot tea in my hand, first thing in the morning is one of the most relaxing, meditative things I've ever done.
Beyond that, anything over 8,500 feet with a view like this always works.
