Fourth day, San Francisco: Berkeley University

Today was "Save the air day', basically it means that on a hot day, all public transportation is free! Bart and I took advantage of that by taking the BART to Berkeley University. The campus is so much more impressive than our campus in Enschede. Just have a look at the pictures to see what I mean.

We have spent exactly $0 today: free hostel breakfast, free transportation, free hostel meal. A hostel is probably cheaper to live in than a regular house; if you do some chores you get a night's stay for free. There are people living here for over six months.
