They say that if you don't like the Washington weather, just wait five minutes. I've got a pair of rain boots for when the weather is at its worst, as we're supposed to get this week. They're cute, but a little tall for me. Of course, that doesn't stop me from wearing them. But with or without wear, rubber bloom can develop on the boots, as you can see on mine. I showed how I clean off the rubber bloom in this blog post.
And while I'm usually pretty bad at remembering to grab a coat unless it's currently raining, I've usually got a thin rain jacket I have in the backseat of my car for when I forget.
