Happy New Year, Questers! While we're ringing in the new year, we'll let Streets Quest help us ring out the old, though much older than just 2012. This time our quest doesn't just concern a bunch of things that aren't there any longer, it concerns some things which have left almost no trace. Not even buildings stand where most of this quest's subjects once were, with one very big exception. We'll have to see how many Questers complete this month's challenge; the last one stumped most of you, with only a quarter of those who started it making it to the finish line. I have confidence that you'll be able to power through this one. For those of you deterred by snowy downtown streets, I want to remind you that codes and badges for Streets Quest are worth the same number of points no matter when you get them, so feel free to save them up for a springtime trip. If you are okay with falling down the leaderboard, that is. On to the clue:
Go to where you could get light bulbs (or most things that plugged into the wall),
And the name on the sign was the same as the man we can thank for those light bulbs at all.
