Hawaii became the United States' fiftieth state on August 21, 1959, a mere seven months or so after Alaska joined the Union. While their climates, size and locations are vastly different, Alaska and Hawaii sort of share a sister-state relationship. Having relatively short direct flights to Hawaii from Alaska also helps. Over the years, my wife has joined me as I have explored many aspects of Hawaii, Kauai, Maui and Oahu.
