It rained as I drove towards my start point, but just as I parked, the rain tailed off, and by the time I was ready to bike away, it had stopped!
I did two circuits, but less than half of the caches I did were Essex Way. Oh well, more for the future!
My left pedal has been sticking; it doesn't rotate freely, and that was a bit annoying, But not nearly as annoying as what happened about half a mile from the car (on the way back at the end of the day). The left pedal completely unscrewed and clunked onto the road! It'll be a fairly minor job to fix it, I think.
57 caches done today, and my elbows are feeling a lot better.
