- A-type stars are among the more common naked eye stars, and are white or bluish-white. They have strong hydrogen lines, at a maximum by A0, and also lines of ionized metals (Fe II, Mg II, Si II) at a maximum at A5. The presence of Ca II lines is notably strengthening by this point. About 1 in 160 (0.625%) of the main-sequence stars in the solar neighborhood are A-type stars, which includes 9 stars within 15 parsecs.

- Hood Canal Bridge (Wikipedia)
The Hood Canal Bridge (officially William A. Bugge Bridge) is a floating bridge in the northwest United States, located in western Washington. It carries State Route 104 across Hood Canal in Puget Sound and connects the Olympic and Kitsap Peninsulas. At 7,869 feet (1.490 mi; 2.398 km) in length (floating portion 6,521 feet (1.235 mi; 1.988 km)), it is the longest floating bridge in the world located in a saltwater tidal basin, and the third longest floating bridge overall. It opened in 1961 and was the second concrete floating bridge constructed in Washington. Since that time, it has become a vital link for local residents, freight haulers, commuters, and recreational travelers. The convenience it provides has had a major impact on economic development, especially in eastern Jefferson County.
