Earth Day Is April 22. Now Go Dig It. Plant In It...Broadcast some seeds in it....Feel and Smell the Earthy-ness in your hands. And for God's sakes enjoy your ownself while you're doing it...whatever "IT" is.
Whatever your thing is, get into the outdoors and go do it. Leave the place like you'd want somebody else to leave it should you visit that place. Preferrably, a little better or no worse than when you got there.
