Blogs, hotels, clinics, parking sites, and local publishers can show one wait, compare 2 to 4 crossings, or publish a history chart.
Choose one path. Every path keeps freshness, direction, and attribution visible.
Start with where it will appear: hotel, directory, article, lobby, or report. We apply a recommended format and width; then choose the crossing and check the preview. Install with one oEmbed link, a no-JavaScript image, or one code snippet. Every wait is labeled as entering the U.S.; outbound travel is not inferred.
Free cards help local travelers and open the full page when they need more detail.
