This is the city -- and it's changing so fast it seems as though any info I put here will be outdated by the time I post it. So, first off, here's the official Callahanicon map showing where the hotel, the airport, the bus station and the Saturday night cookout are.

And here are some links:

Austin Convention and Visitors Bureau -- Planning guide for visitors. The downtown maps (here's the ACVB map; here's a map on the City of Austin site with a pull-down menu giving some other maps) are a few years old and doesn't reflect some changes to downtown (for one, there's a couple more art museums there now).

City of Austin directory -- a set of links to other Austin information sites, not very informative itself
