Good thoughts.

1. Walking is the last resort for me. I could do it and am equipped for it, but before that I'd stay over at work, go to a friends/ hotel, take public transport, call for a ride, cab, bike...Walking is slow and energy intensive.

2. The GHB is supplemented by gear in the car and at work.

3. Knowing the route(s) is important: Not just my highway commute, but alternate ones, bus lines, walking paths etc. And know that alternates are almost always longer.

4. Getting good, timely info is going to be tough; radio? internet? other?

5. Have cash on hand.
