Rainy Day in Flower Mound

With the forecast calling for showers and thunderstorms today, I was wondering what everyone likes to do around town on a rainy or slow day when the usual plans are off. Since many of us have a median commute of about 26 minutes, which is pretty average for Texas, I'm guessing some of us might have a little extra time to explore local spots or try something new - what do you like to do on a day like today?
