Personally, I would love to see this happen. Stanford Stadium is only occasionally used which seems a waste and we do have many soccer fans here, as last Saturday's event proved.
The one thing that must be improved is the traffic control. Whoever is the chief traffic engineer at the City must sit down and work out a plan that will work, unlike last weekend's fiasco.
The City of Palo Alto needs this to happen. Think of the tax revenue we can roll in. Think of the visitors to the City. Think of the value to local businesses, restaurants, etc.
This proposal should be put to the Earthquakes management and let's look forward to professional soccer at Stanford.
