- Axiom of choice (Wikipedia)
In mathematics, the axiom of choice, abbreviated AC or AoC, is an axiom of set theory equivalent to the statement that a Cartesian product of a collection of non-empty sets is non-empty. Informally put, the axiom of choice says that given any collection of sets, each containing at least one element, it is possible to construct a new set by choosing one element from each set, even if the collection is infinite.

- Meadowdale Beach Park - Lunds Gulch (wta.org)
This is a great all-season hike featuring beautiful mature second growth forest and beach access. Hike down a lushly forested ravine with a babbling creek, home to many species of salmon and trout. Follow the creek to its estuary as it empties into Puget Sound. If you extend your hike to the beach, breathe in the serene panorama of Brown’s Bay, Puget Sound, the islands, and the Olympic Mountains. Watch the seabirds and go beachcombing to look for crabshells, anemones, and other treasures.
