SARNIA, CANADA — Around 1,500 Americans participating in the annual Port Huron Float Down were caught in strong winds and were accidentally blown into Canada on Sunday. <br /> <br />The Float Down consists of party goers hopping onto rafts, inner tubes or other floatation devices and just floating down the river from Port Huron, Michigan. <br /> <br />The event was supposed to start at Port Huron’s Lighthouse Beach and end at Chrysler Beach in Marysville. <br /> <br />However, on Sunday, the strong winds and challenging weather conditions caused the Americans to cross over the border and invade international waters. <br /> <br />Some Americans actually tried to swim back to the U.S. because they were worried about entering Canada without proper identification or documentation, according to CBC News. <br /> <br />According to BBC, Canadian officials took six hours and transported 19 bus loads of people back to US Customs and Border Protection. <br /> <br />Sarnia City spokeswoman Katarina Ovens said workers spent several hours cleaning up beer cans, coolers and picnic tables that were washed up on shore. <br /> <br />St. Clair County Sheriff Deputy Steve Campau said as of Monday morning all the participants were accounted for, according to the BBC.
