I would guess that Hell Fish Bonanza is gone except for the final. It had been broken awhile back so the WCFP couldn't follow the trail of way points to the final.
The I39 underbelly could , according to regulations, still be active as it is not 'on' WCFP managed property. It is accessed through the WCFP near by it though and is a worthwhile geocache hunt.
Greenbacks -Georgeous Gorge, has probably been conficated and archieved but was near the final to Hell Fish Bonanza.
Points well taken Marty.
I asked if they would hire me to hunt down any strays but they said they couldn't pay volunteers.
My big chance at being a paid geocache hunter crushed.
