A group of Tucson cycling friends rode a loop from Patagonia to the U.S. Mexico border and back to Patagonia recently. The loop is 50 miles, about 40 of it on dirt roads. It takes in mining ghost towns nestled in oak covered hills, and a broad expanse of high grassland ranches.
Claire and I rode our road bikes to Cape Royal at the North Rim of the Grand Canyon on my birthday. It was a hilly 45 miles ride all at 8000 feet or more. We were the only bicyclists on the road, but there were many motorcycles. One group of three guys from Italy were impressed that we were managing the ride.
