The Four Corners rules are simple; you have 21 days to ride your motorcycle to these four corner cities of the United States; San Ysidro, CA Blaine, WA Madawaska, ME and Key West, FL. You may visit the four corners in any sequence and by any route that you desire. You do not have to return to the first corner to finish the event.

In 2007 we had 87 riders travel 853,691 miles on the tour. That's an average of 7,483 miles each. After converting Kilometers to miles the shortest distance ridden was 6,478 miles by Charles E. Founier of Edmundston, NB Canada and the farthest was Gordon Wilson and his dog Scooter at 9,497 miles.

You must mail from each of the corner checkpoints with the self addressed envelope provided by SCMA to show proof of visit; (a) A gas receipt from a service station in the checkpoint city, (write your motorcycle license number on the receipt). (b) The postmark date, your speedometer reading miles/kilometers, and one phone number from a location listed on the corner map furnished. (c) You must take a photo of your motorcycle at each corner checkpoint. The background must be of a post office, police station or a landmark that clearly shows the checkpoint city name.

The rider's package includes; rules, four corner maps, four stamped envelopes addresses to USA Four Corners Tour. Successful finishers receive a scrap book with the certificates, your photo's in front of each corner landmark. gas receipts, a miles/kilometers recap date sheet of the four corners, and the postmarked envelops. Also included are the fancy finishers pin, small and large cloth patch and SCMA decal showing the four corners logo. This is truly a class event. The Four Corners folks also host an annual banquet in February in the Los Angeles area.
