The possibility of acquiring inexpensive trips to overseas tours
Travelers who come to San Francisco usually do not miss the opportunity to visit the island of Alcatraz.
It has a fort built in the 15th century, which was first used as a defensive structure, and then was turned into prison. It was believed that it was impossible to make an escape from it (although such cases rarely, but still have been).
Overseas trips are now not in such large amounts as many of our compatriots think.
For inexpensive vouchers to Canada and the United States of America, prices are quite acceptable for a considerable number of Russians, and therefore our fellow citizens are increasingly going there with excursion goals.
