    How ParksRadar™ works

    ParksRadar calls each park's day good, some trouble or rough, for that kind of park: from the weather forecast, and from how busy the day looks against that park's own normal. On the map, green is a good day, amber is some trouble, red is a rough day, and black is a park that is closed today.

    Ratings and hours are forecasts, not official figures. Always confirm on the official park site.

    About

    Entrance / day-use fee applies.

    On May 8, 1846, U.S. and Mexican troops clashed on the prairie of Palo Alto. The battle was the first in a two-year long war that changed the map of North America. Although the two countries have developed strong bonds and friendly ties since the war ended in 1848, these neighbors continue to contend with the legacy of the war.
