Make friends, be a Maker at the 50th Anniversary of International River Crossing


It’s almost time to celebrate the 50th Anniversary of GSSEM’s International River Crossing! The annual event is THE event of the year and thousands are expected to celebrate the international friendship between Girl Scouts and Girl Guides! This year’s celebration is Saturday, Sept. 30 from 9 am – 4 pm in Marine City and feature a special twist: a Maker-Inventor Faire!

Attendees are going to love all the activities in store that day! Don’t miss the parade heading down Water Street (for the first time) at 1 pm! The parade will include a police car, a fire engine, two floats, clowns, and animals. Participants can also decorate push me-pull me’s (wagons and strollers) or just walk in the parade with their banners.       

Dance with the DJ runs from 1:30-3:30 pm.  And the fun continues with Stomp Rockets, craft stations, World Centers learning station, Mackinac Honor Guard, and shopping at the on-site Council Shop for t-shirts and trinkets. 

NEW THIS YEAR: Maker Inventor Faire! Show off an innovative project full of imagination and creativity! Troops/groups or individuals get a one-hour timeslot to show and tell about their project, as well as special recognition as a participating Maker at the Maker-Inventor Faire! See flyer for details.  The first 200 girls to sign up will receive a special Maker Inventor Faire patch!
