Yes, street view is very addictive. And also one of the safest ways to achieve some views of the bridges. I was in Alameda county, CA, this weekend and there are old railroad bridges that are accessed on county roads that have conspicuous "no parking, stopping or standing" signs posted for over a mile in all directions. Street view is a tremendous help in such situations.
