yep, i was just scrolling down to see if anybody mentioned that. i've only researched this guy and his treasure hunt very briefly, like an hour total. And, while so much is cryptic, one thing that is very clear is that it's in a place where an old guy could carry a farily heavy box to. That's not down a river bank where you need ropes, or days and days of hiking into the backcountry. 

i bet it's more or less right under our noses...given a little effort.
