Watch out and up

Some time ago a friend of mine was admiring the "romantic icicles of St. Petersburg". She was wondering and obviously disappointed by the fact that we don't have as massive icicles in Finland.

Forgive me for being a boring engineer, but there's nothing romantic in icicles, especially if it falls down and penetrates your skull. Secondly, environmentally conscious person (like this particular friend of mine) should not fantasize about icicles, since icicles are a sign of energy leaks in the building: heat is leaking through the structures due to bad insulation, and the snow on the roof is melting. Once the melted water reaches the cold edge of the eaves, it refreezes and grows into an icicle.
