Tuesday, Nov. 03, 2009 | A new stadium in downtown will only compound the massive traffic and parking problems one sees at Petco, when there is a sellout crowd. With twice as many cars for 60-70,000 people, it will be impossible. The steady breeze that one sees at Petco will only be worse in the winter. There is only one logical place for the new stadium, and that is at the Qualcomm site. The roads, merging freeways, and space for parking are there. Central location for the people from all over this county is there. The facility for SDSU is there. Building a “new” stadium while using the “old” has been done many times in this country á la Yankee Stadium or Stanford Stadium. Jack Murphy and the others who picked that outstanding location were correct. Don’t repeat the Petco mistake and move it elsewhere.
