The Free National Park Junior Ranger Program
At nearly every U.S. National Park Visitor Center, children can pick up a free Junior Ranger activity booklet, complete a few fun nature observations during your visit, and take an official oath with a Park Ranger to receive a collectible wooden or embroidered Junior Ranger badge.
Child Car Seats & Booster Seat Laws
Every U.S. state strictly enforces child restraint laws: infants and toddlers under 2–4 years must ride in a rear- or forward-facing 5-point harness seat, and children up to age 8 (or 4 ft 9 in / 145 cm tall) must use a belt-positioning booster seat in the back seat. You can check your own FMVSS/ECE-approved car seat for $0 on all U.S. airlines rather than paying $15/day to rent one.
