This cache is projected to have a limited lifespan!
Cache is placed near the Forevergreen Road bridge over I-380. Plans are for a highway interchange to be built at this location in the summer of 2018. News articles here and here.
Once construction starts: cache is likely to be muggled, or destroyed, or buried in concrete like Jimmy Hoffa.
Bring your own pen.
Cache contains a travel tag for the FTF.
