Details of this geocache trail can be found at the first cache.
You are looking for a bison.
Unfortunately due to the landowner suddenly blocking a footpath that had been in use for around 20 years, the walk had to be diverted at this point, and the last few caches replaced. This one survived a little longer as it could be reached over the new fence, but now sadly this has been cleared too. You'll have to take my word that it was a good hide! :-)
This series is being made open to all again (rather than premium only) - but caches will be archived as they get damaged or go missing, and the series will eventually be retired. Please look after the caches to preserve them as long as possible, and happy hunting!
