How would I know that I was skiing around big crevasses-I wouldn't be able to see them because of all the snow!
There is a problem in my garden with subsidence from felled trees that were not removed, and the roots rot and collapse. The garden is badly affected, with holes in various places up to a meter across that I have to fill on a regular basis, probably twice a year. I should get someone in to see to it properly, but never seem to find the funds.....
Anyway, as a result it makes me nervous about dips in the ground. By the time I fill mind they can be 6-12 inches in depth, having been filled once that season already. So what about areas that are not filled (is the worry in my mind). It wouldn't take much to make you stumble, twist your leg and get injured.
I realise I could just be a paranoid Annie and I fully accept that fact.
