I went out to check up on "Big Dead Tree" and Bamboo Gone Wild":

"Big Dead Tree" is doing fine. SOmeone had even left a hitchiker
there.
The root ball that the box is hidden is about 3-4 feet across and you
may have to look a bit to find the box. Hell...I placed the box and
it took me 4-5 minutes to find it. It's a round tupperware container
(white)..about 3 inches across....so if you kick some leave/dirt
around, it'll show up.

"Bamboo Gone Wild" could not be found...and for a good reason. There
were huge sand bars and leaves 2-3 feet up the bamboo....obviouly a
small flood had been through/ I will replace it in the next week or
two.
