CO flies to Liberia. Out of Houston. (IAH) Never been to Liberia but I've been to GUANACASTE which borders Nicaragua many years ago. (1974) I think Liberia is in the province of Guanacaste. Lots of neat history there. Did you know that WILLIAM WALKER tried to invade Costa Rica via Guanacaste and got beat back? This when he was self imposed President of Nicaragua back in the day, 1840's when eventually he was killed in Honduras after ship running aground. I happened to see his burial place by accident when my ship pulled into Puerto Castilla near Trujillo. He was shot by firing squad. I'm more recently familiar with San Jose, Alajuela area of Costa Rica. CR is a great place.
