BAXTER — He may be retired and spending winters in Mexico, but Jesse Ventura said he’s far from mellow when it comes to defending his rights. “I’m very vocal,” he said Friday at the grand opening of Discount Tire in Baxter. His appearance at the opening for the new business, which also included Baxter city officials and pageant queens, was prompted by a request from his wife’s niece, Tiffany Diaz. Her husband, Jason, is the store manager. Ventura said family is his “only link to Minnesota” since he’s not a big fan of winter in the north.
