Chicago is a fun place. I hope you have a good time. There's a great grocery store in Chicago called Trader Joe's. It's in other big cities as well. As far as ringworm goes, I got it once from a Persian cat. It made this big ring on my back and I went to the doctor, thinking it might be Lyme's disease. He gave me a phamaceutical sample of an antifungal cream and it cleared the problem right up. The cat had a deficient immune system and had a chronic problem with it. The other cats and I must have developed immunity after one bout because we have never gotten it again. When my goats get it, I wipe it with fungisan and spray with either blukote or athlete's foot spray. The goats do seem to develop immunity to it as well.
