Waiting for our transit day, we decided to go and visit Panama City by car. We wanted to take the famous train but trips for passengers seem to be difficult. Panama City is fun - Samuel was the best travel guide for us - he really thought it through, including a great lunch at the fish market. We spent most of the day at the Casco Viejo, very attractive old town with great bars and spanish colonial buildings, and in the afternoon went to the Bio Museum designed by Frank Gehry.
