I know this stuff is old news to Seattle folks in-the-know, but just this week I've used all three of these and thought 'pon how insanely convenient they are. And the only thing better than insane clowns is insane convenience. I totally missed my calling as a copywriter.
1) BECU's Snapshot ATMs - Man, do I love these. No deposit slips, just pop in your card, press a few buttons, in goes your signed check or cash, and you're done. It'll even spit out a receipt with a snapshot of your check on it (hence the name, duh). Fight the power: join a credit union!
2) ORCA Card - Just so much easier than cash or even a bus pass. No worrying about zones or transfers or switching from KC Metro to Sound Transit or whatever. I'm testing my limits of nonchalance whenever I get on the bus now. Just how little energy can I use to pay my fare? It's a fun game.
3) OneBusAway.org - A few minor glitches and negligible functionality oversights are nothing compared to the fact that this is like having a magic, real-time bus finder in your pocket (or on your desktop). Honestly, once I found this, I rethought our current car situation (we still need a car, but hey: rethinking!). It made me love public transit all over again... for the very first time.
