I ran 3-4 week Med trip to Nicaragua for many years. In 2009, 2 Med students changed their own Tix and flew down 3 days early to go surf in San Juan Del Sur.Probably true. However, when you travel to foreign countries, you need to up your game and triple check yourself and gear prior to going. Lest you end up in the slammer in some foreign land. We aren't in Kansas anymore Toto.
BAD MOVE considering they were carrying $$$$ worth of Medications and Surg Equipment with NO attending faculty or manifest documentation which was required for entrance into the country.
They were jailed together for 4 days at the airport, in a 10'x10' concrete cell w/ a hole in the ground and only 2 "meals" of Rice & Beans/day.
Everything they were carrying was confiscated at the airport BUT I always carry a bottle of Jack Daniels just for times like that.
A good Nica guard will always take the Jack
