Sounds like painting in the garage at my old place, only the power wasn't ever out. Extension cords run from the house with only a few florescent lights wired to the rafters, lol. Carry around a trouble light while painting, roll outside to look over base, push back in and clear and hope you got everything while guess painting (kinda like spraying a bright white when I first started) Luckily haven't had power go out in the middle of a paint job yet, but had enough other sheet happen.
Had the power go out recently here. Waited last minute to do taxes, was the deadline and filling them out online. Power goes out and I lose everything. Luckily the power went back on after 3 or so hours, but then had no internet because cable was still out, had only online forms and instructions to go by and fill out. Call up cablevision, guy can barely speak english and couldn't figure out how to get things going again. Says can have a tech out in three days, meanwhile blowing through minutes on my cell during this long call. Hey buddy, a tech fixing in three days, that isn't going to work. Try to get someone local to talk to and after cursing he trys transfering me, and I am cut off. Cable finally came on a few hours later. If you could only speak to someone local who knows English anymore. I suspected they were having a power outage as I had, If only could have spoken to someone local, could have found that out. Cable vision sucks.
