Just got back from my first ride at Westwood in quite a while. Bit of funny trivia that popped back into my mind:
Bridge #22 was originally a kitchen sink.
When we started building the trail, materials and labor were scarce. I found an old, white ceramic coated sink about 6' long nearby and placed it in the small ravine to serve as a bridge. I filled it with dirt so that bikes could roll over it. I believe it served many months before being replaced by a proper bridge.
