This is a recreation of insane.cache.posse's a nice easy cache...? which had 98 finds and 14 favourite points over 8 years.
You should easily spot the magnetic box somewhere under the rainbow but to claim a find you must sign the log........Now that's going to require teamwork or a tool of the trade and some effort.
Unless you have these items in your 'caching bag' you may need to visit GZ more than once. Not a bad thing as there's plenty to see and do nearby.
Congratulations to Karicka for being the FTF.
