Before visiting any country you should collect some information about its best resorts, traditions and national cuisine in order not to find yourself in difficult or even dangerous situations. The following information will be of some use for you if your next travel destination is Mexico.
Mexico, the capital of the country is situated in the mountains on the height of 2240 meter, so the weather in this city is pretty cool comparing to local sea resorts. Though the population of Mexico city is 20 million people then underground is not overcrowded even during the rush hour. It can be explained by the tendency of riding bicycles in this town. There are even bicycle parking lots on some metro station made to promote this kind of transportation. You can also take a Metrobus which presents a mix of subway and bus. It has the appearance of the bus but moves along a separate line so you should not be afraid of traffic jams. Note, that for women and disabled people the first carriage is meant in order to prevent them from harassment.
