The cache is not at the listed co-ordinates...but in Letterbox tradition, it's a certain bearing and distance away...
Recommended parking is in the geochecker.
Waypoint averaging has been used to set the co-ordinates, but tree cover could be problematic, especially at certain times of the year.
There are three mementos in the cache, one each for FTF, STF and TTF (please be sure to take the right one!).
Please leave the stamp and inkpad in the cache.
