The snow was nt deep ( it had been windpacked from the 50kph winds during the storm ) , but it was smooth and fun . A great improvement over the previous weekend . That night we went back to ChCh with the roads being infinitely better . We suspect it was all the cars with chains that cut the ice up so it eventually melted .
Question: Why were the roads infinitely better that night ?
The answer to the above question:


Because the cars with chains driving on them all day cut up all the snow and ice causing it to melt .
