22-Jan-2003 -- I found myself within a mile of the Concord degree confluence as I headed back to San Jose from an appointment east of Concord, not realizing earlier in the morning that I had come so close to the confluence even though I had driven along the same stretch of highway, just in the opposite direction. Fortunately, I had the 13 closest confluences to home loaded into my GPS (along with the usual number of about 400 local geocaches), so it just popped up as I headed back west along the highway towards Concord to nab this, my second degree confluence visit. My GPS showed the degree confluence at 157 feet, and accuracy with seven good locks on overhead satellites was 17 feet, well within the limits of an acceptable find.

Just head south on Willow Pass Road from Highway 4. Almost exactly a mile down the road is a small crossroads with a no-left-turn sign. About 40 feet to the left is as far as you can go because of the chainlink fence and the posted warning sign. Needless to say, I didn't stick around very long -- probably a wise choice, considering the posting made by the first visitor to the confluence back in 1998 which I hadn't read until AFTER I visited the naval weapons area with a GPS and digital camera in hand....
