MOHAI Presents Shalom! Open for Business: Tales of Jewish Merchants in Washington State 

In partnership with the Washington Jewish Historical Society, MOHAI will be displaying the rich details of Jewish history in the Northwest beginning this Saturday.
Through Mid-January, MOHAI's Linda and Ted Johnson Family Community Gallery will feature photographs, anecdotes, videos, interactive displays, and original artwork from early Jewish immigrants to Seattle, many of whom made their way to the West Coast from Eastern Europe to escape religious and political persecution. From fish peddlers to butchers, bakers, and luggage makers, this exhibit offers a look at the lives and livelihoods of some of Seattle's earliest Jewish families.
MOHAI Presents Shalom!, Sat, July 26, MOHAI, 860 Terry Ave N, $17 (Regular MOHAI Admission).

SummeRun and Walk for Ovarian Cancer
Here's your chance to raise some money to help treat and find a cure for the 5th leading cancer-related killer of women—ovarian cancer.
Only 3 percent of women with cancer have the ovarian variety, but because few effective detection methods have been developed in the past 50 years it has remained a pervasive threat. Run or walk the 5K course and contribute to the Marsha Rivkin Center for Ovarian Cancer Research, an 18-year-old institution bent on finding a way to spot it early because survival rates for ovarian cancer treated in its earliest stages are nearly 90 percent. 
SummeRun and Walk for Ovarian Cancer, Sun, July 27, 6:30am, Corner of Marion and Minor, $35.

Who's Your Transit Hero?
While we at PubliCola are certainly interested in the answer to this question (and we hope it's us), we're not the ones asking. The Transportation Choices Coalition's annual event is coming up on September 11, and this year they're unveiling a new award: The People's Choice Transit Hero. 
Have a say in who wins by voting online, and make sure the person or organization who you believe has done the most to improve Seattle's transportation system gets proper recognition.
