In the Sahara miles from anywhere, a guy walked out of the midday haze carrying nothing but a piece of wood, passed by 50 yards away without looking at us, and headed into the heat. Now HE was bimbling.
It's not required to achieve anything whilst Bimbling, although it's aimlessness is a frequent side effect.
Bimbling can be made a little more business like with a slight hunch of the shoulders.
It is not essential that Bimbling should be a solo sport.
