It won't stop the war, but I've just left a golf-friend who owns a travel company, - he owns about 50 coaches, business is slack through covid, & he told me he is driving one of them himself tomorrow from here, (SW Germany) to Poland filled with medical supplies given by his near Black-Forest town of Freudenstadt and will be bringing around 50 Ukrainian refugees back.
I asked him where they will stay & he said, "We'll find places for them around the town, I might take two or three into my house myself",
I said if we can help, please get in touch, - who knows? :0)
