These are working notes rather than travel writing. Each one exists because the same question kept arriving in enquiries, and the answer was long enough to be worth writing down once: which direction a viewpoint faces, what a permit actually costs, which hour a place is still empty.
Several of them save real money. Photography permits in this country are issued per site rather than nationally, by authorities that do not coordinate: a municipal film office, a parks department and the National Park Service can all have a claim on the same afternoon. San Francisco alone has two entirely separate regimes, because the Golden Gate Bridge approaches are federal land and Alamo Square is not. Knowing that before you plan a morning around a location is worth more than any amount of advice about composition.
Others are about timing, which is the thing people most often get wrong and the thing that costs nothing to get right. The Texas bluebonnets are three weeks nobody can name in January. Mount Rainier’s meadows bloom for a fortnight. Haleakalā sunrise needs a reservation released exactly sixty days out. Washington Street in Brooklyn is finished by half past seven in July.
If your question is not answered here, ask it directly — the answer usually turns into the next article.
