Find your way to the wormhole and experience the audio-visual proof of travel through time...
IMPORTANT: Please note that the cache is not at the published co-ordinates, GZ is accessible via pedestrian rights of way only, no fences need to be crossed. Please take care, keep the final location secret... and post NO PHOTOS of GZ please
You are looking for a box in a camo bag with original contents of log book, pencil and sharpener, FTF trophy, First to Find Lucky Horseshoe TB, and a few beetle swaps
You can check your co-ordinates on geochecker. This is set as a fuzzy solution with a 25ft/8m margin of error - only a small margin, I know, but you will appreciate why once you're at GZ.
Congratulations to Zeusfaber for a very quick First To Find...
a torchlight find too 
and pretty much exactly 24 hours after I'd hidden the cache and thinking it makes quite a good night cache really...
You can validate your puzzle solution with certitude.
