As a business traveler, you usually know where you are going and the best way to get there, but sometimes it’s faster to take public transportation depending on the situation. It is always good practice to know your options, especially when it is the difference between getting home or staying another night in a foreign city.
That is why I find this webpage an invaluable resource to keep in your back pocket, just in case. It would be quite handy for anyone visiting a new city, as well, so be sure to pass it on to your fair weather travelers :-)
The travel website, Amadeus provides some other travel-related functionality, but the subway maps (in PDF and Word) are clearly a stand-out gem. Here’s a sample for Chicago:
Be safe and get home – that’s my motto.
UPDATED 03/21/2010: Updated links to coverage maps
If you haven’t jumped on the 3G bandwagon, you’re missing out. Spend your unexpected delays finishing up things you have to do, so you have more time to do things you want to do. It’s not like you have too many choices when sitting in an airport terminal or cab.
All the major carriers offer some version of broadband access over the 3G network, usually focused in heavily populated cities across the states. If you’re heading somewhere less populated, you can check ahead to see what type of broadband coverage to expect.
Follow the links and save yourself the trouble of digging through the carrier websites:
Verizon happened to include a coverage map without the need to supply a zipcode.

I’m keeping my fingers crossed for reliable and ubiquitous broadband access regardless of where you are. Until then, it’s all about the coverage maps.
