We decided not to be deterred by the rain and set out on search of this one despite this morning's weather. Before we'd even started on the UVW, our car decided to make a protest: the alarm/immobiliser stopped working. (It came back to life later in the day, as the car dried out.)
GPS reception was next to nothing under the trees, so we paced the distance to the cache and found ourselves to be surprisingly accurate: we found the cache in the first place we looked. Due to the rather large water droplets that were falling from the trees, we hastily signed the log and returned the cache whence it came. Even so, it would probably be good if the next dry-weather visitors would ensure that everything is moisture free!
Thanks for a very wet and muddy cache! We're sure that DILLY THE CAT would love to explore this area.
