There are new parking meters downtown. Each space has a numbered sign, and you pay at a central kiosk; there's one per block. You can print out a receipt if you want one (I like their look... it's a very happy font and layout), but you don't have to. When I was plugging the meter last time a meter maid rolled up in her car and I asked her about it; she held up her iPhone and showed me the app that showed her which cars were paid and for how long. "You don't need a receipt, I just look at this!"
