When the last cache in Thomas Guide grid 475 went away, I decided it was up to me to create one to allow those who want to complete the Portland-Vancouver Thomas Guide Grid Challenge (GC2NFBX) to be able to do so.
Nabbing this cache will bring you to a part of Sauvie's Island that I bet you've never been to; I sure hadn't.
Parking for this cache is within an area marked as "Parking Permit Required; OR Dept of Fish and Wildlife".
I seeded the cache with a bunch of swag and a brand new (activated) trackable.
The black latches on the cache container open FIRST FROM THE BOTTOM and THEN from the top.
Please make sure that when you leave the cache the latches are latched on both the bottom and top.
