The Panama border crossing went pretty smooth and we made it on through to David, where we spent the night. There is actually only one real highway crossing through Panama, but we hope to take some side trips after going to check out the Panama Canal. We went down to the canal to watch the big ships go through the Miraflores Locks, and that is quite an engineering marvel to me. Tomorrow, we will start working our way slowly back up to the states, going through Belize and then up the opposite side of Mexico from where we entered. While still in Panama, we are hoping to check one of the waterfalls and do some birdwatching if we can.
