HIGH MUGGLE FACTOR HERE, hence the D rating, which I may tweak after I see how the first several finders fare on this one. I suggest this as a 'middle of the night' find, or at least before 10am when the business VERY nearby opens! Then, barring a possible security patrol, it may seem remarkably easy.
In the movie, they were trying to race to the treasure, which was buried 'under a big dubya'.
Well...look for 'the big ecks'!
...or, really, the LITTLE ecks. ;)
One difference from the movie, it is NOT buried, for X in fact marks the spot, so very very exactly!
Again, the high D rating is for the HIGH muggle factor here and the fact that you are completely exposed 360 degrees, between the drivethru nearby and probably to security cameras! Best efforts to protect the cache, please. ;)
