When I got up in the morning they was slight drizzle. I hoped it would stop by the time I go for my morning walk, un encumbered with an umbrella.

Got my wish.

While on a three lane concrete road saw a phenomena which intrigued me. 

Of the tree lane concrete road, the centre lane was still wet and glistening where as other two lanes on either sides were absolutely dry.

All the lanes were built almost at the same time. Same concrete mix. Same process. Same contractor, then why such diverse reaction to water. One

retaining wetness others bone dry.

Unable to come up with logical explanation.  

Wet centre lane. Dry side lanes.
