nature walk
"I have met with but one or two persons in the course of my life who understood the art of Walking, that is, of taking walks—who had a genius, so to speak, for sauntering, which word is beautifully derived “from idle people who roved about the country, in the Middle Ages, and asked charity, under pretense of going à la Sainte Terre,” to the Holy Land, till the children exclaimed, “There goes a Sainte-Terrer,” a Saunterer, a Holy-Lander. They who never go to the Holy Land in their walks, as they pretend, are indeed mere idlers and vagabonds; but they who do go there are saunterers in the good sense, such as I mean. Some, however, would derive the word from sans terre without land or a home, which, therefore, in the good sense, will mean, having no particular home, but equally at home everywhere." (Henry David Thoreaux, Walking)
"Every walk should offer some knotty problem for the children to think out––”Why does that leaf float on the water, and this pebble sink?” and so on." (Charlotte, Mason, Vol. 1)
