She is well know for her perseverance and a DNF means she will come back until she finds the cache or stays for endless time until she got it! She has definitely more patience as so many others and doesn't give up easily!
The easiest way to the cache will be via blue/green/red and get on the unmarked trail at the waypoint.
The trip is fairly easy, but the difficulty comes from the requirement to sign the logbook...take a seat and have fun! I bet JATLink will like it!
