If you would like a trustworthy local contact for a guide/ride, I definitely recommend Mark!  Getting a local guide to take us around the area was pretty cost effective even compared to taxis, plus we got a feel for the local flavour and culture, met a few musicians, and didn't waste our time trying to figure out which places to try! He picked us up and took us to the shops first, and brought us to a local side-of-the-road place for the most delicious local food!! We also went to tour an "mj" farm (my request), found authentic excellent coffee (also my request!), and stopped at local bar for a real feel for the area. He also booked us on the YaMon catamaran the following day - truly a must do, such a great deal! Highly recommended.
