Walking also gives you time to smell the flowers, and to see what's happening around you. Neighborhoods are infinitely fascinating, but most people blow through life so quickly that they only see the Suburban that's taking its lane out of the middle in front of them.
On my way to work today, I passed a homeless man in the park near the Lake Merritt BART station in Oakland. That's not surprising-- there are usually a handful of homeless people hanging out there every day. What caused me to do a doubletake was the way he was dressed-- white dress shirt, black pants, red suspenders, and a red bowtie. He might also have been wearing red socks; I can't remember now.
From a block away, he looked like he was wearing a santa suit.
It was hot today; I wonder if he was still wearing the bowtie at 4 p.m?
