Ambling around

This gentleman certainly seems to think so, for the slippers anyway. Maybe he left his pipe at home. This is a great example of how people here are pretty carefree with what they wear while riding - this fellow's gear could almost pass for pajamas. Rather than ATGATT, it's more like NGATT. On the other hand though, they don't go around crashing bikes anywhere near as often as Kiwis do, at least from what I can tell reading the forums here!
Quite apart from the slippers, I couldn't believe how this guy could have his bare legs just inches away from the hot cylinder head...
