Pedro, I and others around here appreciate what you contribute. You have access to something we don't have and get to see women naked in public all the time. This is only a dream to someone like me. And you are kind enough to share it with us. By the way, that must have been killer to see a woman clothed on the street and then getting to see her naked when she gets to the beach. You have captured some really hot babes this year.
If we got enough people chipping in $2 - $5 (a paltry sum for what you contribute) we could indeed buy you a nice camera. Perhaps a contribution pool using Paypal. Of course, I don't know how the forum admins would feel about it. But what you contribute does bring people to OCC. A plan of this type would benefit us all. A miniature HD video camera could capture video and high quality still photos. It would have to be silent in operation and have mechanics that don't make it susceptible to damage from the sand as you require.
These are just thoughts of mine. You may or may not agree.
