On Thursday where I am at, here in Nova Scotia, it was a really nice day... (Started out nice and sunny, and warm for February) I went on a bit of a driving adventure with a friend, and it was warm enough that when the weather turned bad, it turned foggy. It felt more like Spring than the middle of February.
The fog screwed with visibility a bit for driving, especially when it turned dark out, but that just means it was warm enough for fog. So not bad.
