Biological weathering...

This is a great example of root damage to pavements, which is why I took this shot on the way to the shop this morning.
It is for using with my teaching - a good example of biological weathering! (teacher off-duty still looking for materials...)

I then managed to forget to take any more pictures for the rest of the day - so - this is the blip although it was not really meant to be!

Swam early, worked in the shop in the morning, started sorting Alex's packing in the afternoon athen had a barbecue in the evening.
