Owner Mario Martinez said people were travelling as far away as Queens and New Jersey to get their Mexican music fix and he wanted to offer these tunes closer to home.Then one day after the record shop opened, Martinez brought in a pair of cowboy boots, a style popular among native Mexicans, Martinez included.A pair of boots grew to a few. Soon he had hats, shirts and a growing demand. Six years ago, he moved the record shop two stores down to a smaller location and opened Rudy El Vaquero in its stead.According to the 2010 Census, Hispanics make up more than 50 percent of the Bronx population, including a fast growing number of Mexicans.
