The original Sherwood Field did not last as long as expected, going missing after a run of about eight months. Hiding a replacement was an obvious choice, as the field and walking path here really is fantastic, but replacing the cache in its old hiding spot would have resulted in it going missing. Thus, the cache was moved to a brand new (and better!) hiding spot, hopefully being more muggle proof and more hidden this time around. It's also been relisted as a new find so new folks can come check the spot out and old finders can come back and make the find in a new spot.
You're looking for a hanging bison tube. As mentioned before please BYOP and do not over screw the cap! Doing so will cause the o-ring to break, and therefore possibly result in a wet log. Please be careful!
