i do, but to be honest, i am one of these people that doesnt believe in the value of making preparations unless they are major (e.g. building self sustaining house etc) and couldnt afford to do so anyway even if i wanted to.
best i can do is to prepare my family for short term things that last a couple of days like power cuts, severe weather - so i have candles, matches, torch, food and things like that.
of course, id rather be located a few miles from civilisation in a solar/wind powered house that was self sufficient in water etc. also, but that is just a pipe dream unless i won the lottery.
