Some obscure holidays we could live without, like national ham day or toothbrush day, but this might be a good one.

Today is National Margarita Day, and several Texas spots plan to help you celebrate.

The NationalMargaritaDay.com site gets into the history behind this awesome holiday, and says margs were probably developed in the 1930s or 1940s, but the frozen drink wasn't invented until the 1970's, when a creative bartender used an ice cream machine to crank out the first frozen margarita.  Thanks dude, for giving us this creative way to pack about a fourth of our day's calories into one delicious, limey, beverage.

On the Border in Tyler (4301 Broadway) will celebrate as one of the official party spots, according to the National Margarita Day website.  The On the Border location in Texarkana will too.  Participating On the Border locations across the country will have $2 margaritas today.

You might not get the $2 marg today without a drive, but the holiday still might be a good excuse to hit happy hour in Lufkin or Nac. These things must be properly recognized.   And if you want to have friends over and whip up your own drinks, click HERE for some recipes.

A national drinking holiday?  The Monday blahs have no chance today.
