Glendora Mountain Trails Traverse/ Professional Review and Guide
"The Glendora Mountain Trails Traverse takes advantage of the city of Glendora’s short but nifty trails system, making a clockwise loop on a mixture of dirt trails and paved roads. This was the only ride in the book I was unable to complete, because the Colby Trail was closed when I visited during summer 2014.
The trail was closed because of the January 2014 Colby Fire, which burned nearly 2,000 acres in the area. The fire, started by three men who lost control of their campfire, destroyed five houses, injured one person, and led to the evacuation of 3,600 residents. The timber and brush had not burned since the 1960s and was ripe for kindling."
