Most of the people who will be reading this are familiar with what the bay bridge looks like, but for those who don't, a photo is in order. The western span (in the foreground of the photo) has four suspension towers, with heavy duty cables running from peak to peak, and a mass of smaller cables suspending the bridge itself. There are two decks-- the upper deck handles westbound traffic, and the lower deck has eastbound.
On the south side, near the final "dip" of the suspension cables, there's a ladder leaning against the side of the bridge against the main support cable. It looks like it's just an ordinary extension ladder, nothing special, and it's been there for weeks.
Every time I drive by this, I shudder at the thought of climbing this ladder. EEEKKKK!
