[billericaybill]

I dont think the ballast is the wrong colour ! If its Wales it is A) either raining in which case the ballast colour is OK or

it has just finished raining in which case the ballast colour is still OK. Now if it was Billericay which I believe is the driest spot in UK it would quite likely be a lighter colour for half of the time.
