A few places I like:
- Trans continental flights - my favorite, seat in business class, get the cube out and don't stop for hours, that's 10 hours of non-stop solve or training

- Driving, sure. OH is definitely more dangerous than BLD! I have to stop that. Lonely morning commute is fine, but traffic at 6PM is really distracting (the other way around?)
- Insomnia. 2 AM what was that about F2L case? Slow down, look ahead. 3 AM get up, scramble, solve, again. Again. 4 AM TV time (repeat PLLs) Science channel. What was StefanPoshmann saying yesterday? (I'm a fan of Stefan!) 5 AM I have to get rid of that cube. 5:01 where is my white one anyway? crunch crunch crunch. 6 AM I'm late for my OH driving on the bridge... M, T, T, W, F, S, S. Well, on S, S, I have one more hour of crunching before the kids get up AH AH AH!
