Heehee...you all got keep Candles and Torchlights in the house or not?
Seriously, I haven't had a Blackout in my block ever since I moved in 12 years ago.

A couple of Power Trips here and there when any of the Electrical Appliances "misbehaved" but no Blackout.
The only "Blackout" my house had was a few weeks ago when the Kitchen Light Switch choose to let the Electricity flow out of it onto the plastic casing. Had to use Candles to light up the Kitchen and toilet at night for a few days till the Switch Casing was changed completely.
