Icing is scary. Have had just about enough experience with it to realise I don't like it.
The situation is as bookworm describes it. There are many times that the weather is actually doable if you look beyond the first impressions you get.
De-icing is a bit like having an IR in two ways.
The first is that with the ability/equipment comes the realisation that quite often things were not as bad as you thought and you don't need it.
The second is that there will always be a next level of hindrances stopping you from being truly 'all weather' proof.
I realised that a little while ago and now just accept that there will always situations which mean you can't go. As I never 'have' to be somewhere at any cost I just live with that.
It is not just a matter of equipment level but more so the realisation that the weather one could potentially tackle with it would require more experience and currency than I will have by doing some 100-150 hours per year.
