Yes, but only if the last Mix of a cascade is in the US. Otherwise you may use a web-proxy: There you put your desired address into a web form and the corresponding web site is loaded via the web-proxy into your browser. However, you must be aware that a lot of the web-proxies are spying out user data (passwords, information regarding credit cards...). As a result you should use them only if it is absolutely necessary and if your transmitted data shall not be kept secret.
