My sacred spaces are anywhere with trees, especially large trees, spreading trees, old growth, on flat ground, with water nearby. Locally, those places are Big Trees Forest Preserve, Heritage Park, the Etowah Mounds, the river next to Thousand Hills coffee, a few places in the Atlanta Botanical Gardens, a few places on Red Top Mountain, and others to a lesser extent (Olde Rope Mill was one before they destroyed it, as was Dupree Park), and some I haven't discovered (but can feel that they're there). Farther away, there's this place in Anstruther Scotland where I bonded with this wildly overgrown bush that was more like a tree, Hannah's mum's garden in Belgium, the Angel Oak in Charleston, and Muir Woods (despite it being overrun with tourists even) and the Pfeiffer Big Sur State Park in CA, and these magnolias that were outside of the Botanical Gardens in DC when I was a kid. Those with old trees are automatic but there are others, little pockets of magic, found anywhere, like this one concrete retaining wall in Atlanta next to a parking lot with a few small trees and vines hanging down the wall in places, or the lot where Koronah built an altar and Kylei and I began to really build our connection, or the Marietta square (in which Kylei and I imbued and/or found a lot of magic), and I'm sure there are others that I can't readily bring to mind (not to anyone: if I've mentioned a sacred place to you and didn't write it here please remind me).
I enjoy sharing them, and usually prefer it to being alone there, because I like to be able to turn to someone and say, "do you feel/hear/see this?" and vice versa. But I only like sharing them with people who will be very intake-oriented, who will be there for the place, who will be very present and in-the-moment. And of course people who do not litter, break things, take things without asking, or take things that would damage the forest. I do like to talk, but I like it to be the kind of talking one might do in an art gallery, only occasional, thoughtful, and about what is being observed and felt. I also need them to expect that my attention is going to be 80-90% on the place and I will need to spend at least part of the time silent and will probably need to take pictures (that is a huge part of how I process important things); I had a terrible experience once with someone who expected otherwise so I've learned to communicate this beforehand! Occasionally I feel the need to reconnect with myself and then I might go to a sacred place alone, but it is the exception.
