Sponsor Plateau Jewelers gave away beach balls, a tradition for the Sammamish business that dates back 10 years.

For the last several years, owner Kelly Jensen has brought a map of the states and a world map so people can document with little star stickers where they’ve taken their beach balls. According to the map, the colorful balls have been all over, from Canada to the UK and China.

The weekly concerts in Pine Lake Park, located at 2401 228th Ave. S.E in Sammamish, continues Thursdays through August.

The last concert is Aug. 27.
