Levi’s Stadium exists. The voters of the City of Santa Clara approved its construction via Proposition J. I voted yes. To see what we approved, the Stadium Authority and the 49ers should have an open house for the citizens of Santa Clara without any strings attached, like a fee ($20 for residents, $25 for the rest). Is that too much to ask? This could be seen as good public relations for if the supporters of the stadium see what’s inside, the naysayers will have less to whine about.
