Welcome to YT! I've been to your site as well in the past. I actually inquired you when you had no puppies available [unfortunatley]. I'm sending you a PM about your boy. All your Yorkies are beautiful btw.
As for the situation in MI. I'm not sure exactly where you're located but I live in SE Michigan and the only complaint I've seen is just the gas scare, like it is all over the county.
Although I don't like the cold weather MI isn't SO bad.
