Have to add this, because its really really true - but worms mate up on the racecourse, at a certain time of the year, they congregate on the surface its ghastly to observe. It has to be a certain temperature and just after it has rained and then they appear conjoined in some ritualistic fest....... its like those ants living under the paving stones - theres more of them than there is of us.....
Littlestone that was a really good worm story.
