The agency that operates the Edward Jones Dome on Friday rejected an improvement plan for the 17-year-old stadium proposed by the St. Louis Rams. The St. Louis Convention & Visitors Commission said in a brief statement that it believes it is in "the best interest of the community and the Rams to engage in meaningful dialogue over the next two weeks, and looks forward to the opportunity to do so at the earliest convenience of Rams management." Arbitration begins if no agreement is reached by June 15, and the arbitration process could last through the end of the year.
