On Saturday ds1 spent the morning at a History Centre about 80 mins drive away with the teens in his archaeology group.
Today he spent the morning being trained and then the rest of the day helping out the local archaology group (all adults) to rinse some of their archaeological finds in their flotation tank (ie. spent the day shloshing water and mud around despite his awful cough and cold).
Next week he is off to help out at a local archaeological mini-dig on one day and on another day to do a recce for some test pit digging over an hour away.
Maybe it's just me, but there seems to be a common theme going on here.
