Sweetheart of the Rodeo
This is a program for 4th graders. The child completes a short quiz and gets a free pass for all federal parks, lands, and waters. The pass is good for the entire year and covers multiple people in the car. (The current pass is good through Aug. 31, 2018, but I’m sure there will be a new deadline soon.) There are partner agencies like BLM, Amtrak, etc. offering discounts with the card. There also are resources for teachers on the site.
