May be an off-the-wall opinion, but I think if you were to contact Mitch and tell him that you were coming up, he might actually show you around and LET you take pictures. I'm not of the opinion that a clandestine operation is necessary.
Johnny. Thank you for your offer about going back to the PCFG site. I will put in 150,00 USD. I can make a wire transfer to your bank account couple of days in advance before you make the trip. I will just need the name of your bank, owner name, account number and routing number. best regards (Karel Oliveira)
