The border crossing was lively.  I saw a Panamanian pigeon fight, a plastic chair I was sitting in spontaneously disintegrated in front of a bunch of people but I was smooth in my recovery and the border patrol police tore our bus apart for 90 minutes looking for drugs. So we are running super late on a normally 16 hour ride. They even took the spare tire out, deflated it, stuck a proctology camera in and gave it a good colonoscopy.  They took all our bags off the bus and let their German shepherd sniff around.
