It seems we correctly identified the street where the president would arrive and managed to effectively surround it.
Protesters force Bush to move Stanford meeting
San Jose Mercury News
President Bush's visit to Stanford University's Hoover Institution was quickly moved to another location after more than 1,000 protesters converged around the Hoover tower. The White House said the protesters blocked the only road into the central areaof the campus where Hoover is located, which forced a meeting with several Hoover fellows to be moved to the campus home of former Secretary of State George Shultz, a Hoover fellow who organized the gathering.
The motorcade instead traveled to the house, which is on the outer edge of campus. The change in plans delayed the president's arrival by about 15 minutes. Protesters said they were disappointed that the President would not see them and accused the President of sneaking around to avoid them.
