Piper, this is a dream, finding a toilet that flushed
in Desaguadero was hard enough, phone calls took 10
tries to complete, do you really think a Groun
Penetratin Radar can be found nearby? It doesnt matter
at this point, the government would put you in jail as
they prefer to let the meteorite rot.
