When travelling my default position is to walk unless there is a compelling reason not to such as distance over 3-4 kms., weather or safety. This has occasionally frustrated colleagues who prefer a car or taxi.

A few months ago on a business trip a colleague was perplexed when I eschewed his cab and walked to the office. The city is a warren of one-way streets and rush hour traffic can be heavy. We left the hotel at the same time and I was calmly sipping my coffee when he arrived at the office. The next morning we both walked.
