Recreational Bikers at the Border

From Cyclotour Guide Books:
"Crossing the Detroit River is a problem for both residents of Detroit & Windsor; and touring bicyclists. There are no bike racks or baggage holds on the buses which go through the Tunnel (only folding bikes can be brought inside the buses); the Ambassador Bridge absolutely forbids bicyclists on either the roadway or the walkway; and there sometimes is and sometimes is not a Bridge/Michigan DOT pick up truck to take cyclists across the River.
Our most recent communiqué with the Detroit-Windsor Truck Ferry has made us very sad. The Canada Border Services Agency and the US Customs and Border Protection Agency have prohibited the Truck Ferry from transporting bicyclists & their bicycles.
Now, crossing the Detroit River involves making a sign and using your thumb to hitch a ride. Grab a bit of a discarded box and write in 3 in./7.3 cm to 5 in./12 cm. high letters: To Windsor or To Detroit. Wait at the entrance/on ramp to either the Bridge or the Tunnel with your thumb extended and the sign on your chest. A friendly motorist will stop and help you out. Thumbing your way across the Detroit River can not be considered an adequate way for bicyclists to continue their journey."
