Austin is the capital of Texas, a good 80 miles northeast of San Antonio on the Colorado River in the heart of Central Texas. You come for the live music almost every night, for brisket from Michelin-starred barbecue joints, and for the cold springs of Barton Springs right in the city.The city center is compact: From the Capitol, Congress Avenue leads straight down to Lady Bird Lake, the impounded Colorado River. South of the Congress Avenue Bridge lies South Congress with its shops, food trucks, and the Continental Club. East of Interstate 35 is East Austin, where many of the best barbecue and taco spots are located today.In March, the city is crowded and expensive during the South by Southwest festival, as it is on weekends with University of Texas home games in the fall. From May to September it is hot, but then every evening the bats fly out from under the Congress Avenue Bridge.
