Got dinner plans tomorrow? Starting at 4 p.m. on Thursday, Purple Cow at Preston and Royal will donate 15 percent of all its sales to the Dallas Derby Devils. It includes alcohol sales.

DDD is the original Dallas-Fort Worth roller derby league with a roster of more than 120 active skaters. In fact, it’s the largest flat track derby team in the south.

It’s hard not to respect these fierce females who compete in bouts for sell-out crowds and get pretty bruised up in the process. I remember interviewing Preston Hollow resident Meg Weathers with Assassination City Roller Derby for our March 2010 issue about hardcore athletes. She called her battle scars “badges of honor.”

The promotion is a good excuse to indulge in some of Purple Cow’s yummy burgers and milkshakes. The fried apple pie is heavenly.
