The Johnsons live in Cairo and are originally from Minnesota. Foreigners and Egyptians alike have swamped the airport looking to escape the country as street protests continue.

A U.S. citizen holds a placard and an Egyptian flag in Tahrir Square, Cairo on Feb. 1. The Egyptian army has said it will not fire on protestors as they gather in large numbers in central Cairo demanding the resignation of Egyptian President Hosni Mubarek.

The U.S. State Department has evacuated more than 1,200 Americans from Egypt aboard Government-chartered planes, and expects to fly out about 1,400 more in the coming days, we report today.

But at least one U.S. citizen decided to join the protesters in Tahrir Square today, where al-Jazeera correspondent Dan Nolan described the scene as 'kinda like an Egyptian version of Woodstock'.

UPDATE: Thanks to the readers of PhotoBlog, we now know that the woman in the second photo is Lisa Roscoe, who was raised in San Francisco and now lives in Cairo with her Egyptian husband. She heard that we had posted her picture and got in touch with us via the comments section below.

In an exclusive interview with msnbc.com's Ian Johnston, Roscoe explains why she joined the protests.
