Try this link for now. I created this map as a test. It’s a public map to anyone with this link. So all of you should be able to click on it and add your genreal location. It is not public on the web meaning that if you search for it on google you won’t find it. You can reach it only through this link below. I also added the location of a few common nurseries just for reference. We can create as many categories as we’d like. I would like to find a plant hardiness zone overlay. try it out.
EDIT, I took Alan’s suggestion and created a new thread. I’m still not sure if the map will work but feel free to try it out and report back to the new thread.
