Help
So my friend and I go to the park to practice witchcraft, because we love be surrounded by nature when doing spells and such. We have this secluded part that is off the trail fenced off (by a short fence you can step over) and surrounded by vegetation. There's this clearing in the middle of it with a tree, and this is where we hang out. We cleaned up the area, by bringing trash bags for recycling and trash, we planted native flowers, and left water for the animals. We haven't destroyed the area at all, but we did have a little alter type set up, with a pentagram drawn in the dirt for spells and a Boulder surrounded by small rocks where we leave our offerings (small flowers, bird seed, etc.). We haven't harmed anyone or the area, yet when we came back to the spot today, someone had destroyed the trees branches and leaves, displaced logs, kicked over and scattered the rocks by our offering, kicked the pentagram out of the dirt, and took the candle. We're pretty upset, as it took us weeks to build that spot up and make it feel like a safe spot to practice witchcraft without judgment. We thought that we had done a good job at protecting the area but apparently not. I understand that it was probably a few kids and maybe they were scared because of the stigma around witchcraft, so I'm not exactly mad at them. I don't wish them any harm, however, as my friend and I are new to this, we don't know how we should approach this.
If anyone has any suggestions, or spells that we can use to prevent this from happening again we would greatly appreciate the advice! Thank you!!
