LH is digging in Edinburgh's Canongate with DaveH.

Often archaeologists will be sent to sites with little or no thought as to facilities (ie the dreaded windfarm)... On this site however, this is not a problem. In all his illustrious archaeological career, I don't think Dave has ever been this well served by washing and toilet facilities. Apparently the urinals flush every 15 minutes and you can set your watch by it....
