If you want to surf privately and anonymously at pretty much any place without installing any software try TorPark.

Download Torpark,  put it on a USB Flash keychain/drive,  plug it into any internet terminal whether at home, school, or public and run Torpark.exe to  launch a Tor circuit connection, which creates an encrypted tunnel from your computer indirectly to a Tor exit computer, allowing you to surf the internet anonymously, without any one knowing which sites or locations you are visiting. The Tor service also allows you to reach sites that are blocked by your corporate/school firewall & access control systems.

The software and the anonymizer service "Tor" is completely free for use.
