Cowboys Dancehall, a popular country music venue routinely among the most lucrative local alcohol-selling establishments, has filed an emergency bankruptcy petition to stall a foreclosure sale scheduled for next week. The San Antonio dance hall was scheduled to be sold at a foreclosure auction July 5 after defaulting on two property loans totaling $ 7.5 million made through two deeds of trust in 2007 and 2008, according to Bexar County records.
