The Summer Solstice of 2020 is my husband's and my 17th wedding anniversary, and we're spending it hiking up to the top a mountain, to get closer to the sun, of course! We're traveling light, and certainly using mostly traditional, ancient, natural energy, such as our bodies, the sun, fresh wild foods, and the wind to keep us going. At night, we're using solar powered headlamps when necessary, but our eyes are well adjusted to seeing in the darkness, and we rarely ever need to use the lights, except to make sure that when we go to the bathroom, we don't accidentally pee or poop on a napping porcupine or something. We've also got a small, very low energy Basic Internet Gizmo (a small BIG!) that is powered by the movement of our legs as we walk around, with the option to use solar power and an extra battery for a signal boost, if we need it, but since this is a personal celebration, we're focusing on communicating as intimately with each other, and leaving the rest of the busy and fast-paced human world behind.
Once we get to the top of the mountain, we spend a while thanking the sun for giving us it's energy, and then spend some time thanking each other for giving us our energy, and then, of course, we get to work passionately using all that stored up natural energy for the rest of the day and night... :-)
