Unfortunately we have had too much of a good thing and the sun disappeared today, only to be replaced with rain!
It had stopped when we arrived at site at about half past nine, but then it started up again and didn't stop. The problem is that we were very close to finishing the last concrete base, but it was just too wet to clean up. Plus the wet ground would lead to some false resistivity readings, so we thought it was better to abandon site for the day!
We will be back tomorrow to see what happens with the weather and we all have our fingers crossed!
