If the statute does not involve a suspect or quasi-suspect classification, then rational basis review applies, in which a court must ask whether the statute is rationally-related to a legitimate governmental interest.
Autumn Foliage Color. The Process of Leaf Color Change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
Trees respond to such factors as autumn drying conditions, temperature change, altered sun position, and light. It takes approximately two weeks to begin and complete the fall color change so timing and a little luck are essential for the perfect view.
