When I was a kid, the frustration when riding the subway was that I couldn't get the radio on my Sony Walkman. There was no signal.
Today that frustration has morphed into the sad fact we can't get a cell signal on the subway in Toronto. Most of my life has been spent on the Bloor line which, as you'll see in the handy TTC cell service map below, has very few mobile-friendly pockets.
