This is a Letterbox Hybrid, with a log which you can stamp with your special letterbox stamp; then use the cache’s enclosed rubber stamp for your logbook. Please sign the logbook too. You can treat this as a regular cache by simply signing the log if you wish, as it is a hybrid, but it will be recorded as a Letterbox. Be sure to leave the stamp and inkpad in the container, as they are not trade items and must be replaced if they go missing.
From here, you have a view of the U.S. Border Patrol offices.
